39da47e435 fix: detect and fail on oversized zip entries instead of silent truncation
Replace io.LimitReader with a new readZipEntry helper that reads one extra
byte to detect when content exceeds maxZipEntrySize (500MB). This prevents
silent data corruption where partial file bytes would be stored as if the
upload succeeded.

The import now fails with ErrFileTooLarge instead of accepting truncated
content for attachments and background blobs.

c2cf5ba1c5 fix(restore): validate migration data before wiping database
Move archive validation (migration file existence and slice bounds
check) before the database wipe. Previously a malformed archive
would first destroy the database and then panic, leaving the
instance in an irrecoverable state with total data loss.

Now the migration data is fully parsed and validated before any
destructive operations occur.

3c0ea7099e fix(restore): validate database file names in zip archive
Check that database entries in the zip have a .json suffix and a
non-empty base name before slicing the extension off. This prevents
a panic from index-out-of-range when the filename is too short.
Also use TrimPrefix instead of ReplaceAll for correctness.

7971500467 fix(restore): sanitize config file path to prevent zip slip

12dca5f0b0 fix(restore): reject zip entries with path traversal sequences
Validate all zip entry names during restore to reject entries

write files outside the intended extraction directory.

b3d8a56364 fix: use caller's session in LDAP syncUserGroups to avoid nested transactions
syncUserGroups created its own db.NewSession() internally while being
called from AuthenticateUserInLDAP which already has an active session
with writes. In SQLite shared-cache mode this causes a lock conflict.

Pass the caller's session through instead, and add s.Commit() before
db.AssertExists calls in LDAP tests.

2a10b22c5c fix: use session-aware file creation to avoid nested transactions
files.Create() and files.CreateWithMime() internally create their own
sessions and transactions. When called from within an existing
transaction (now that db.NewSession() auto-begins), this creates nested
transactions that deadlock on SQLite.

Switch to files.CreateWithSession() and files.CreateWithMimeAndSession()
to participate in the caller's existing transaction instead.

49bba7f830 fix: eliminate nested database sessions to prevent table locks
Refactor functions that created their own sessions when called from
within existing transactions, which caused "database table is locked"
errors in SQLite's shared-cache mode.

Changes:
- Add files.CreateWithSession() to reuse caller's session
- Refactor DeleteBackgroundFileIfExists() to accept session parameter
- Add variadic session parameter to notifications.Notify() and
  Notifiable.ShouldNotify() interface
- Update all Notify callers (~17 sites) to pass their session through
- Use files.CreateWithSession in SaveBackgroundFile and NewAttachment
- Fix test code to commit sessions before assertions

c9c250fb1c fix: add missing Commit() to write callers
After NewSession() auto-begins a transaction, callers that perform
writes must explicitly call Commit() for changes to persist. Without
this, writes are silently rolled back when Close() is called.

Affected callers:
- user deletion notification cron
- caldav token generation/deletion
- token cleanup cron
- mark-all-notifications-read endpoint
- saved filter view cron
- project background delete
- typesense reindex
- export cleanup cron
- task last-updated listener
- saved filter view listener
- SSO team cleanup cron
- migration status start/finish
- background set/remove handlers
- orphaned task position cleanup
- file creation

8ee069a2a3 feat: add session-based auth with refresh token rotation
- Login creates a server-side session and sets an HttpOnly refresh
  token cookie alongside the short-lived JWT
- POST /user/token/refresh exchanges the cookie for a new JWT and
  rotates the refresh token atomically
- POST /user/logout destroys the session and clears the cookie
- POST /user/token restricted to link share tokens only
- Session list (GET) and delete (DELETE) routes for /user/sessions
- All user sessions invalidated on password change and reset
- CORS configured to allow credentials for cross-origin cookies
- JWT 401 responses use structured error code 11 for client detection
- Refresh token cookie name constants annotated for gosec G101

249b651692 fix: treat archived TickTick tasks as done during import
TickTick uses status "2" (Archived) for completed tasks that were
subsequently archived. The import only checked for status "1"
(Completed), causing archived tasks to be imported as open despite
having a completion timestamp.

6dbc108be8 feat(auth): allow LDAP authentication with anonymous bind (#2226)
As discussed on Matrix, Vikunja currently prevents users from using LDAP
authentication if the server allows anonymous binds (common in local
environments like YunoHost). The application would previously trigger a
`log.Fatal` if `AuthLdapBindDN` or `AuthLdapBindPassword` were left
empty in the configuration.

#### **How this fixes the problem:**

* **Validation:** Removed the strict requirement for Bind credentials in
`InitializeLDAPConnection`.
* **Connection Logic:** Updated `ConnectAndBindToLDAPDirectory` to
attempt an `UnauthenticatedBind` from the `go-ldap` library when no
credentials are provided.
* **Safety:** If a Bind DN is provided, the behavior remains unchanged
(authenticated bind).

#### **Testing:**

* Tested manually on a **YunoHost** instance by replacing the binary.
* Confirmed that Vikunja now successfully starts and authenticates users
via the local LDAP (localhost) without requiring a service account.
* Added a basic unit test in `pkg/modules/auth/ldap/ldap_test.go` to
ensure the initialization logic doesn't crash with empty credentials.

*Note: This is my first contribution to a Go project (assisted by an LLM
for syntax). Feedback on code style is more than welcome!*

79d0942780 fix: use DelPrefix in upload avatar FlushCache to clear all cached sizes
FlushCache was using keyvalue.Del with the base key
(avatar_upload_{userID}) but the actual cache entries are stored with
size suffixes (avatar_upload_{userID}_{size}). The Del call targeted a
key that never existed, so cached avatars were never invalidated.

Switch to keyvalue.DelPrefix to delete all size variants at once,
matching the pattern the gravatar provider already uses correctly.

c93fa1b4ae test: add failing test for upload avatar FlushCache
The test populates the cache with multiple size-suffixed keys

because FlushCache uses Del with the base key which doesn't match
the actual size-suffixed cache keys.

e90cb2631d fix(auth): remove unnecessary fields from JWT token payloads
Remove email, name, emailRemindersEnabled, and isLocalUser from user JWT
claims, and isLocalUser from link share JWT claims. These fields are never
used from the token - the backend always fetches the full user from the
database by ID, and the frontend fetches user data from the /user API
endpoint immediately after login.

Also simplify GetUserFromClaims to only extract id and username, and
remove the now-unnecessary email override in the frontend's
refreshUserInfo.

  in io.NopCloser
- Task attachment: change NewAttachment parameter from io.ReadCloser to
  io.ReadSeeker

39b4568bc5 refactor: centralize HTTP error handling (#2062)
This changes the error handling to a centralized HTTP error handler in `pkg/routes/error_handler.go` that converts all error types to proper HTTP responses. This simplifies the overall error handling because http handler now only need to return the error instead of calling HandleHTTPError as previously.
It also removes the duplication between handling errors with and without Sentry.

🐰 Hop along, dear errors, no more wrapping today!
We've centralized handlers in a shiny new way,
From scattered to unified, the code flows so clean,
ValidationHTTPError marshals JSON supreme!
Direct propagation hops forward with glee,
A refactor so grand—what a sight to see! 🎉

a4aad79f53 fix: TickTick import (#1871)
This change fixes a few issues with the TickTick import:

1. BOM (Byte Order Mark) Handling: Added stripBOM() function to properly handle UTF-8 BOM at the beginning of CSV files
2. Multi-line Status Section: Updated header detection to handle the multi-line status description in real TickTick exports
3. CSV Parser Configuration: Made the CSV parser more lenient with variable field counts and quote handling
4. Test Infrastructure: Added missing logger initialization for tests
5. Field Mapping: Fixed the core issue where CSV fields weren't being mapped to struct fields correctly

The main problem was in the newLineSkipDecoder function where:
- Header detection calculated line skip count on BOM-stripped content
- CSV decoder was also stripping BOM and applying the same skip count
- This caused inconsistent positioning and empty field mapping

Rewrote the decoder to use a scanner-based approach with consistent BOM handling.
