AuthMiddleware::authenticate() only re-read Remote-User/Remote-Groups
(and thus is_admin, via UserModel::syncUserFromAuthelia) when
$_SESSION['user'] didn't exist yet. Once a session existed, every
subsequent request only checked the idle timer — never re-validating
against current Authelia/LLDAP state. An admin's group membership
revoked in LLDAP, or a logout at the Authelia proxy, left their
already-open session with full access for up to SESSION_TIMEOUT (5h
default), with no way to force early revocation short of clearing the
server-side session store.
Added PRIVILEGE_RESYNC_INTERVAL (default 5 min, matching
UserModel's own cache TTL) and a resyncPrivileges() check on every
already-authenticated request past that interval: re-reads the current
request's forward-auth headers (enforcing the trusted-proxy check
again, same as a fresh login), and either destroys the session and
redirects to re-auth if the user no longer has any required group, or
re-syncs is_admin/groups/display_name/email if they do. Best-effort if
this particular request doesn't carry forward-auth headers at all
(skips silently rather than force-logging out, retried next interval).
UserModel::syncUserFromAuthelia() has its own 5-minute in-process
cache keyed only by username (not by the groups being synced), so a
naive re-call during a resync would have kept returning the
pre-revocation cached result for up to 5 more minutes — invalidated
that cache entry immediately beforehand to guarantee a real re-sync.
Verified against real MariaDB across a fresh login, a same-interval
request confirming no premature resync, an admin-privilege-revocation
mid-session (is_admin flips to false in both session and DB, verified
via a direct query), and a full group-membership revocation (session
destroyed, redirected to re-auth, confirmed the request never reaches
past that point).

Trusted-proxy hardening (defense-in-depth for Authelia forward-auth):
- AuthMiddleware now only honors Remote-* identity headers when REMOTE_ADDR
is in a configured TRUSTED_PROXIES allowlist; otherwise it refuses with 403
and logs an 'untrusted_proxy' security event. Previously anything that could
reach PHP directly could spoof Remote-User/Remote-Groups and log in as admin.
- New config TRUSTED_PROXIES (comma-separated, from .env). Empty = enforcement
off, so this is backward compatible until the allowlist is set on a host.
Requirements checks (so a PHP upgrade dropping an extension can't silently
break features like avatars again):
- config/requirements.php: single source of truth for min PHP version and
required extensions (ldap, mysqli, curl, mbstring, fileinfo, json).
- scripts/check_requirements.php: CI script that fails the build if the
environment doesn't satisfy them.
- New 'requirements' CI job installs those extensions and runs the check;
deploy now depends on it.
- api/health.php: adds php_extensions + php_version checks so production
monitoring surfaces the drift (returns 503 if a required extension is gone).

- TicketModel::getAllTickets() now accepts optional $user param and applies
getVisibilityFilter() so non-admin users cannot see internal/confidential
tickets they lack access to from the dashboard listing
- DashboardController passes $GLOBALS['currentUser'] to getAllTickets()
- clone_ticket.php: move Content-Type header to top so all error paths send
correct JSON content type
- AuthMiddleware: filter group names from HTTP header to [a-z0-9_-] only,
preventing header injection via malformed group names
- add_comment.php: return HTTP 201 on success, 500 in catch block
- update_comment.php, delete_comment.php: return 500 in catch blocks

Security:
- Fix IDOR in delete/update comment (add ticket visibility check)
- XSS defense-in-depth in DashboardView active filters
- Replace innerHTML with DOM construction in toast.js
- Remove redundant real_escape_string in check_duplicates
- Add rate limiting to get_template, download_attachment, audit_log,
saved_filters, user_preferences endpoints
Bug fixes:
- Session timeout now reads from config instead of hardcoded 18000
- TicketController uses $GLOBALS['config'] instead of duplicate .env parsing
- Add DISCORD_WEBHOOK_URL to centralized config
- Cleanup script uses hashmap for O(1) ticket ID lookups
Dead code removal (~100 lines):
- Remove dead getTicketComments() from TicketModel (wrong bind_param type)
- Remove dead getCategories()/getTypes() from DashboardController
- Remove ~80 lines dead Discord webhook code from update_ticket API
Consolidation:
- Create api/bootstrap.php for shared API setup (auth, CSRF, rate limit)
- Convert 6 API endpoints to use bootstrap
- Extract escapeHtml/getTicketIdFromUrl into shared utils.js
- Batch save for user preferences (1 request instead of 7)

Session security improvements in AuthMiddleware:
1. Secure Cookie Configuration:
- HttpOnly flag prevents JavaScript access to session cookies
- Secure flag requires HTTPS (protects from MITM)
- SameSite=Strict prevents CSRF via cookie inclusion
- Strict mode rejects uninitialized session IDs
2. Session Fixation Prevention:
- session_regenerate_id(true) called after successful authentication
- Old session ID destroyed, new one generated
- Prevents attacker from using pre-set session ID
3. CSRF Token Regeneration:
- New CSRF token generated on login
- Ensures fresh token for each session
These changes protect against session hijacking, fixation, and
cross-site attacks while maintaining existing 5-hour timeout.
