Call license.Init() after database initialization and before the web
server starts. Call license.Shutdown() during graceful shutdown to stop
the background check goroutine.
Implement the license validation system with:
- Server communication with retry logic and exponential backoff
- In-memory state management for feature flags and user limits
- Cached validation with 72h expiry stored in database
- Background goroutine with adaptive check intervals (24h/1h)
- Graceful degradation to community mode on failure
- Instance ID generation and persistence
Parse the top-level `attachments` array in WeKan board JSON exports,
group them by card ID, base64-decode the payload, and attach the
resulting files to the generated tasks so they land in Vikunja as
task attachments. Orphaned attachments (cardId with no matching card)
are silently skipped; decode errors are logged and skipped.
The four boolean OIDC provider fields (emailfallback, usernamefallback,
forceuserinfo, requireavailability) were parsed with a strict .(bool)
type assertion. That works for YAML/JSON config where leaves are native
bools, but fails for every other input path: env vars always arrive as
strings, and GetConfigValueFromFile (used by the *.file Docker secret
convention) also always returns strings. The assertion would silently
zero the field for emailfallback and usernamefallback, and log an error
and zero the field for forceuserinfo and requireavailability, which is
what #2599 reports.
Extract a small parseBoolField helper that accepts both native bools and
strings (via strconv.ParseBool) and logs a parse error from each call
site. This also fixes the previously-silent drop of stringified
emailfallback / usernamefallback values — those now log an error if the
input is garbage, matching the behaviour of the other two fields.
Fixes#2599
Regression test for #2599. Exercises getProviderFromMap with native
bools and with stringified booleans ("true"/"false"/"1"/"0") for all
four boolean provider fields — emailfallback, usernamefallback,
forceuserinfo, requireavailability. From env vars and from the
GetConfigValueFromFile path every leaf arrives as a string, so the
current .(bool) assertion silently zeros these fields.
MySQL 8 rejects CAST(... AS int) (only SIGNED/UNSIGNED/CHAR/... are
accepted as target types), causing /api/v1/projects, /api/v1/tasks,
and /api/v1/labels to return HTTP 500 for every authenticated user on
MySQL 8. SQLite, Postgres, and MariaDB lax mode silently accepted the
expression, which is why the regression (introduced in e3045dfd0,
shipped in v2.3.0) passed CI — the mysql CI matrix leg uses
mariadb:12, not real MySQL 8.
Replace the two CAST(all_projects.is_archived AS int) expressions in
the recursive project CTE with MAX(CASE WHEN ... THEN 1 ELSE 0 END),
which is dialect-agnostic and needs no cast on any supported backend.
Fixes#2589
Regression test for #2589. Locks the contract that getAllProjectsForUser
exposes inherited is_archived for child projects of archived parents and
filters them out when getArchived=false, exercising both the MAX(...)
column expression and the HAVING MAX(...) = 0 filter.
The OIDC callback handler previously issued a JWT without ever
checking TOTP state. For installations with EmailFallback (or
UsernameFallback) enabled, this allowed an attacker who could
authenticate at the IdP with a matching email to log in as a local
user with TOTP enrolled, bypassing the second factor entirely.
HandleCallback now runs enforceTOTPIfRequired after resolving the
user and before any team sync writes, returning 412/1017 when the
passcode is missing or invalid. Clients resubmit the OIDC flow with
the totp_passcode field populated.
Fixes GHSA-8jvc-mcx6-r4cg
Extracts a TOTP gate that the OIDC callback will use to enforce 2FA

The TestProject_ReadAll/search case on the ParadeDB path was still
expecting 6 results, but adding fixture project 43 (child of project
10) means the recursive CTE now pulls it in as a descendant whenever
the fuzzy search matches project 10. The non-ParadeDB branch was
already updated to account for this (+1, asserting project 43 is in
the result); the ParadeDB branch was missed.
CI was failing with "should have 6 item(s), but has 7" on the
test-api (paradedb, feature) job. Bump the expected length to 7 and
add the matching Contains assertion for project 43.
No fixture or production-code changes.
GHSA-2vq4-854f-5c72 / CVE-2026-35595: the recursive permission CTE
cascades Admin from any owned ancestor, so a user with Write on a
shared project could reparent it under an attacker-owned root and
resolve as Admin on the moved project via the new parent.
Require Admin on both the moved project and the new parent whenever
parent_project_id is set to a non-zero value that differs from the
stored value. The gate lives in UpdateProject rather than CanUpdate
because CanUpdate is reused by permission-check-only callers
(buckets, webhooks, task ops) that pass stub &Project{ID:...} values
with ParentProjectID=0 and never commit a reparent — gating there
would spuriously trip the check for every such call.
Only non-zero ParentProjectID is gated: the generic update handler
binds a fresh struct, so an omitted parent_project_id is
indistinguishable from an explicit 0. Detach-to-root via the generic
endpoint is therefore out of scope for this fix and is tracked as a
follow-up (needs a pointer field to disambiguate).
Covers GHSA-2vq4-854f-5c72 / CVE-2026-35595: attackers with direct or
inherited Write on a project must not be able to reparent it under their
own tree nor detach it to root. Also pins the legitimate rename-with-Write
and owner-detach flows so the upcoming fix does not regress them.
Adds project 43 as a child of project 10 so tests can exercise the
"inherited Write via parent" path exploited by GHSA-2vq4-854f-5c72.
User 1 has Write on project 10 via users_projects id=4 and therefore
inherits Write on this child via the permission CTE.
The test previously fetched the attachment from https://vikunja.io/testimage.jpg,
which caused flaky failures in CI when the external host was unreachable
(context deadline exceeded). Serve the local testimage.jpg via httptest and
temporarily allow non-routable IPs for the SSRF-safe client so the test is
hermetic and deterministic.
Builds an in-memory export zip with a 2 MB payload and a data.json
that claims size: 0, then asserts neither the honest 2 MB row nor
the forged 0-size row ends up in the files table. Covers
GHSA-qh78-rvg3-cv54.
The hard-coded 500 MB per-entry cap meant operators who set a tighter
files.maxsize could not actually enforce it on imports. Derive the cap
from files.maxsize with a floor so data.json / filters.json / VERSION
entries can still be read when the configured limit is tiny.
Clamp the uint64->int64 conversion and the LimitReader cap so absurd
configuration values do not overflow into MinInt64 and cause
io.LimitReader to treat every entry as EOF.
Import metadata is attacker-controlled and can forge a small size to
bypass the attachment size limit (GHSA-qh78-rvg3-cv54). Compute the
size from the decoded content instead of trusting a.File.Size.
Task/project duplication and the Todoist migration were passing stored
or API-reported sizes into NewAttachment. Derive the size from the
actual buffered content so every caller matches the hardened boundary
behaviour (GHSA-qh78-rvg3-cv54 defence-in-depth).
Authoritative size now comes from the reader instead of the caller's
claim in CreateWithMimeAndSession. The migration import path accepts
attacker-controlled metadata (GHSA-qh78-rvg3-cv54), so trusting
realsize for the limit check allowed oversized uploads to be accepted
and stored.
measureReaderSize leaves the reader seeked to 0 so the measured value
matches the bytes storage backends will actually write.
Drives the login endpoint through 11 failed TOTP attempts against user10
and asserts the account ends up locked in the database, then verifies a
subsequent login with a valid TOTP code is rejected with
ErrCodeAccountLocked. Exercises the GHSA-fgfv-pv97-6cmj regression
against the real handler path.
Verifies that HandleFailedTOTPAuth locks the account after 10 rolled-back
caller sessions (the regression from GHSA-fgfv-pv97-6cmj), and that the
persisted password reset token can unlock the account via ResetPassword.
The failed-TOTP handler shared the login request's xorm session, and the
login handler rolled that session back after a failed login. The status
change to StatusAccountLocked was silently discarded, so the account was
never locked regardless of how many failed TOTP attempts arrived.
HandleFailedTOTPAuth now opens its own session and commits independently
of the caller. The login handler rolls back its session before invoking
the handler so the lockout write can acquire a write lock on SQLite
shared-cache.
Also handles the Redis keyvalue backend returning the attempt counter as
a string instead of int64, which would have prevented the lockout path
from ever running on Redis.
See GHSA-fgfv-pv97-6cmj.
Add MaxTaskRepeatAfterSeconds (10 years in seconds) and reject any
create/update that tries to store a value outside [0, cap] with a new
ErrInvalidTaskRepeatInterval (error code 4029). Defense-in-depth
alongside the arithmetic fix in addRepeatIntervalToTime: keeps stored
values well away from int64 overflow and bounds the range of inputs
a future refactor could trip over.
Exercises updateDone end-to-end with a 1900-01-01 due date, 1-second
interval, and asserts the call completes in well under a second.
Catches any regression that reintroduces the O(n) loop in
addRepeatIntervalToTime (GHSA-r4fg-73rc-hhh7).
addRepeatIntervalToTime used to advance t by whole intervals via an
unbounded loop. A repeating task with an ancient due_date and a
one-second interval required billions of iterations per task update,
turning completion of such a task into a trivial denial-of-service
(GHSA-r4fg-73rc-hhh7). Compute the number of intervals directly, with
guards for zero/negative durations, saturated time.Sub, and int64
overflow.
Covered by TestAddRepeatIntervalToTime, including the 1900-01-01 PoC
case.
Multiget REPORT requests would happily return tasks from projects
different from the one in the href, even though GetTasksByUIDs now
filters by access. Drop any returned task whose real project_id does
not match the project ID parsed from the href path segment.
Hardening for GHSA-48ch-p4gq-x46x.
Even with the GetTasksByUIDs authz filter in place, a user with access
to multiple projects could read a task from project B by requesting it
under project A's URL. Enforce that the task's real project_id matches
the project ID parsed from the CalDAV URL path and 404 otherwise.
Adjusts the Delete Subtask test to use the correct URL project for
uid-caldav-test-child-task-2 (which lives in project 38, not 36);
the previous URL only worked because of the authz gap being closed.
Hardening for GHSA-48ch-p4gq-x46x.
Previously GetTasksByUIDs returned any task matching the UID regardless
of the caller's access, letting any authenticated CalDAV user read any
task by guessing or knowing a UID. Filter by accessible project IDs at
the SQL level using the existing accessibleProjectIDsSubquery helper.
Fixes GHSA-48ch-p4gq-x46x.
Task titles, project titles, team names, doer/assignee names, and API
token titles were interpolated raw into Line(...) calls whose content is
rendered to HTML by goldmark and then sanitized with bluemonday UGCPolicy.
UGCPolicy intentionally allows safe <a href> and <img src> with
http/https URLs, so a title containing Markdown link or image syntax
would survive sanitization as a working phishing link or tracking pixel
in a legitimate Vikunja email.
Introduce notifications.EscapeMarkdown, which prefixes every CommonMark
§2.4 backslash-escapable ASCII punctuation character — including '<' so
autolinks like `<https://evil.com>` are neutralized before reaching
goldmark — with a backslash. Apply it to every user-controlled argument
of every Line(...) call in pkg/models that feeds into an i18n template,
and to the hand-built "* [title](url) (project)" Markdown link in the
overdue-tasks digest notification.
Also escape the migration error string in MigrationFailedNotification,
an additional sink not listed in the advisory (error messages can carry
user-controlled content from the external migration source).
Subject(...), Greeting(...), and CreateConversationalHeader(...) are
left unchanged: Subject is passed directly to the mail library and is
not markdown-rendered, Greeting is rendered via html/template's built-in
HTML escaping without markdown, and the conversational header is
sanitized as raw HTML by bluemonday in mail_render.go.
Fixes GHSA-45q4-x4r9-8fqj.
Task titles, UIDs, descriptions, categories, organizer usernames, alarm
descriptions, relation UIDs, and the calendar name were concatenated raw
into the VCALENDAR text. A task title containing CR/LF could plant new
iCalendar properties (ATTACH, X-INJECTED, VALARM, etc.) that CalDAV
clients would parse as legitimate calendar data.
Introduce escapeICalText, which escapes backslash, CR/LF, semicolon, and
comma per RFC 5545 §3.3.11, and apply it at every sink in ParseTodos,
ParseAlarms, and ParseRelations. Each Category is escaped individually;
the comma that joins categories is the literal list delimiter and stays
unescaped. The now-redundant regexp-based LF handling in the DESCRIPTION
branch is removed.
getCaldavColor is hardened at the same output boundary: non-hex
characters are stripped before interpolation so CR/LF in a crafted color
string cannot inject new iCal property lines, closing a gap where
upstream HexColor validation only bounds length and does not reject
control characters.
Fixes GHSA-2g7h-7rqr-9p4r.
The previous hasAccessToLabel implementation ran `Get(ll)` against a
label_tasks LEFT JOIN with no ORDER BY, which meant the database was
free to pick any matching row. When a label had multiple attachments,
or when access was granted via the creator branch while the label also
had label_tasks rows pointing at inaccessible tasks, the picked row
could belong to a task the caller could not actually read.
That led to two concrete problems reported on the follow-up review of
GHSA-hj5c-mhh2-g7jq:
1. maxPermission (exposed as the x-max-permission response header)
could be derived from a task the caller has no access to, ending
up as 0 or lower than the caller's real best permission on the
label.
2. Task.CanRead on a dangling/inaccessible task could return an
error and surface as a 500, even though the label itself was
perfectly readable via the creator branch.
Split the logic instead:
* Use `Exist` for the boolean access check, using the same carefully
grouped `And(Eq{labels.id}, Or(accessibleTask, creator))` cond.
* Compute maxPermission by selecting the label_tasks rows whose
task lives in a project the caller can access, then iterating
those tasks with `Task.CanRead` and taking the maximum.
* Fall back to PermissionRead when the access was granted via the
creator branch and no accessible task attachment exists.
hasAccessToLabel built its WHERE clause by chaining xorm session .Where,
.Or, and .And calls. xorm flattened those to `WHERE A OR B OR C AND D`,
which under SQL precedence evaluates as
`A OR B OR (C AND D)` — so the `labels.id = ?` predicate only narrowed
the project-access branch. The standalone
`label_tasks.label_id IS NOT NULL` branch leaked every label with any
label_tasks row to any authenticated user, and the
`labels.created_by_id = ?` branch leaked any label the caller had ever
created regardless of the requested id.
Rewrite the query using explicit builder.And / builder.Or grouping so
the label-id scope wraps the entire disjunction, drop the bogus
label_tasks-is-not-null branch, and keep the creator branch only for
real user auths. Replace Exist(ll) with Get(ll) so the resulting
LabelTask row is populated and the follow-up Task.CanRead check that
computes maxPermission actually runs; fall back to PermissionRead when
the match came via the creator branch and no task row is joined.
End-to-end regression test for GHSA-96q5-xm3p-7m84 / CVE-2026-35594: mints
a JWT for a link share via the real helper, then deletes the share row and
invokes the real ReadAllWeb handler to prove the full request path (not
just the unit-tested GetLinkShareFromClaims) surfaces the revocation.
Also fixes a pre-existing stale literal in the TestLinkSharing test fixture
struct: linkshareRead declared Hash="test1" while the actual fixture row
id=1 uses Hash="test". The old code never looked at the DB so the mismatch
went unnoticed; after the fix it would cause every link-share webtest that
used linkshareRead to fail hash validation.
Previously GetLinkShareFromClaims built a *LinkSharing entirely from JWT
claims with no DB interaction, so deleted shares and permission downgrades
took up to 72h (the JWT TTL) to take effect. The permission and sharedByID
claims were trusted blindly.
GetLinkShareFromClaims now takes an *xorm.Session, looks up the share via
GetLinkShareByID, verifies the hash claim against the DB row, and returns
ErrLinkShareTokenInvalid when the row is missing or the hash mismatches.
The permission and sharedByID claims are discarded; the DB row is
authoritative. GetAuthFromClaims opens a read session for the link-share
branch, mirroring the existing API-token branch.
Token creation and the JWT format are unchanged, so already-issued tokens
keep working except when the underlying share has been deleted or its hash
no longer matches.
Fixes GHSA-96q5-xm3p-7m84 / CVE-2026-35594.
CanDoAPIRoute's non-CRUD fallback branch compared a path-derived
permission name to the token's permission strings without checking
the request method. A token with projects.background (registered for
GET /projects/:project/background) could therefore invoke DELETE on
the same path. The same method-confusion affected the whole
/projects/:project/views/:view/buckets[/:bucket] cluster, where a
token with projects.views_buckets (registered for GET) authorized
PUT, POST, and DELETE on any accessible view's buckets.
The matcher also leaked CRUD permissions between parent and nested
sub-resource groups. When the request targeted a nested CRUD resource
(e.g. projects_teams, projects_shares, projects_users, projects_views,
projects_webhooks, projects_views_tasks, tasks_assignees, tasks_labels,
tasks_comments, tasks_relations, tasks_attachments, teams_members),
the matcher fell back from the specific group to the parent's permission
list but then looked the permission name up inside the sub-resource's
RouteDetail map. The effect was that a token holding only projects.read_all
also authorized GET on every nested projects_* list endpoint, and the
same held for create/update/delete and for the tasks.* family.
Rewrite the matcher to iterate the token's own permissions and accept
only when the stored RouteDetail's (Path, Method) matches the request.
This removes all the path-derived group guessing and makes the stored
detail the single source of truth. Preserve the tasks.read_all quirk
(one permission, two list endpoints) as an explicit two-path allowlist
inside the loop.
Extract a GetAPITokenRoutes accessor so the new property-based webtest
can consume the same snapshot served by GET /api/v1/routes.
Add TestAPITokenMethodMatching in pkg/webtests: using the live echo
router and the live apiTokenRoutes map, it iterates every advertised
permission against every registered route and asserts the matcher
accepts iff the stored (Path, Method) matches. Any future collision
introduced by a new non-CRUD route on a shared path will be caught.
After this change, previously-dead permissions like
projects.background_delete, projects.views_buckets_{put,post,delete},
other.avatar, other.ws and caldav.access start working as their UI
labels imply. Tokens that relied on the over-broad background /
views_buckets grants, or on cross-cluster CRUD bleed-through, will
lose the extra access - that is the fix.

When a repeating task dropped on the done bucket is already in the
view's default bucket, the upsert would try to UPDATE with an
unchanged bucket_id. MySQL reports 0 affected rows for unchanged
updates, so upsert fell through to INSERT and hit the unique
constraint on (task_id, project_view_id).
