XSS / security:
- markdown.js: sanitize footnote labels to a safe slug before using them in
id/href attributes. Labels are captured before the HTML-escape pass, so a
label like x"><img onerror=...> broke out → stored XSS (the earlier quote-
escape fix didn't cover this path). Verified neutralized.
- RateLimitMiddleware: only trust X-Forwarded-For / X-Real-IP when REMOTE_ADDR
is a configured trusted proxy, and use the rightmost (proxy-appended) entry.
Previously any client could rotate XFF to escape the per-IP rate limit.
- .env.example: document TRUSTED_PROXIES so fresh deploys aren't fail-open on
the Authelia forward-auth spoofing protection.
Correctness:
- notifications.php: my previous assigned-to LIKE fix anchored only on '}', so
BULK assignments (logged {"assigned_to":N,"bulk_operation_id":..}) produced
no "assigned to you" notification — now matches both '}' and ',' delimiters.
- notifications.php: implement the documented @mention notifications (query
action_type='mention' rows for the current user); they were never delivered.
- NotificationHelper::notifyWatchers: guard unchecked prepare() so a missing
ticket_watchers table can't fatal the request after its DB write committed.
- AuditLogModel::getTicketTimeline: JSON_UNQUOTE the extracted ticket_id so
comment events actually match (string vs JSON-number comparison never did).
- AuditLogModel/audit_log.php: CSV export no longer silently truncates to the
1000-row UI cap; uses a dedicated higher export limit.
- DashboardView: quick-preview drawer read .ticket-link from the title cell
(which has none), so the title was always blank — use the cell text.

- upload_attachment.php: derive stored file extension from validated MIME type
instead of user-supplied filename, preventing executable extension attacks
(e.g. a PHP file renamed to evil.txt would now be stored as .txt)
- CustomFieldModel.php: fix bind_param type string in updateDefinition()
'sssssiiiii' (10 chars) → 'sssssiiii' (9 chars) to match 9 SQL placeholders
- RateLimitMiddleware.php: replace MD5 with SHA256 for rate limit file hashing
- user_preferences.php: add httponly, secure, samesite=Lax flags to ticketsPerPage
cookie to prevent XSS/CSRF cookie theft
