Four interrelated gaps in the same rate-limiting path:
- #80: RATE_LIMIT_DEFAULT/RATE_LIMIT_API were defined in config.php but
RateLimitMiddleware never read them (hardcoded class constants
instead), and they weren't in .env.example — a deployer editing them
saw zero effect with no documented way to actually change the limit.
- #81: Bearer traffic was rate-limited purely by a shared IP bucket
(the session-based half was a no-op for stateless clients, since a
fresh session starts on every request). Two different API keys from
the same host/NAT egress IP shared ONE bucket, so a chatty or
misbehaving key could 429 a completely unrelated key's traffic.
- #82: X-RateLimit-* headers reported the meaningless session counter
for Bearer clients instead of whatever bucket actually governed them.
- #83: RateLimitMiddleware::check() called session_start()
unconditionally, before ApiKeyAuth even runs — continuous session-file
churn and an unnecessary Set-Cookie on every stateless API request,
using un-hardened cookie defaults since it runs before
AuthMiddleware's hardening (which Bearer requests never reach anyway).
Fixed as one pass since they're the same code path: config.php now
reads RATE_LIMIT_DEFAULT/RATE_LIMIT_API from .env (added there too,
documented); the middleware now extracts the raw Bearer token
(independent of ApiKeyAuth, so no DB round-trip needed before rate
limiting, and it works whether or not the token later turns out
valid) and rate-limits it via its own per-token bucket instead of
starting a session — the existing IP-based bucket still applies
underneath as defense-in-depth against volumetric abuse from one
network path, but each distinct key now gets real isolated headroom.
getStatus()/addHeaders() report that per-token bucket for Bearer
requests instead of the session counter.
Verified: a Bearer request creates zero session files (confirmed via
real session-directory file count before/after); two different keys
from different IPs are fully isolated (one exhausting its own 120/min
bucket has zero effect on the other); a config-driven RATE_LIMIT_API
override (e.g. 5) is correctly honored for session-based (non-Bearer)
traffic; X-RateLimit-* status correctly reflects the per-key bucket
for a Bearer request.

TRUSTED_PROXIES ships empty in .env.example, which disables
AuthMiddleware's reverse-proxy allowlist entirely — a fresh deployment
that doesn't explicitly set it has zero verification that
Remote-User/Remote-Groups headers actually came from the trusted
Authelia proxy. Anything that can reach the app directly (a
misconfigured firewall rule, an exposed container port, SSRF from
another internal service) can set Remote-User: admin and fully
impersonate any user with zero authentication. The enforcement logic
itself was already correct; this was purely a dangerous, easy-to-miss
default.
Added a boxed, unmissable warning around TRUSTED_PROXIES in
.env.example (previously just an inline comment easy to skim past),
added the same warning to README's setup instructions (which didn't
mention this variable at all), and added a Check 8 to api/health.php
that reports a 'warning' status when TRUSTED_PROXIES is empty, so a
deployment that forgets it doesn't go unnoticed after the fact.
Verified against real MariaDB via a running server: the health
endpoint correctly reports 'warning' when empty and 'ok' once set.

Primary fix (#63): added the 5 env vars config.php reads and README
documents but .env.example never listed: MATRIX_DOMAIN,
SYNAPSE_ADMIN_URL, SYNAPSE_ADMIN_TOKEN, MATRIX_NOTIFY_COMMENTS, and
MATRIX_NOTIFY_ASSIGNMENTS. A deployer following only .env.example had
no indication these existed, silently missing watcher Matrix DMs and
comment/assignment notifications.
While verifying the fix by actually running .env.example through
parse_ini_file() (what config.php calls), found this file could not
be parsed at all — a real, currently-live outage for anyone following
its own first-line instruction ("Copy this file to .env and fill in
your values"):
1. PHP's ini parser treats "#" comments as fragile: punctuation like
parentheses or quotes inside a "#" comment can throw a syntax error
even though the line is meant to be inert. The file's header
comment itself (and 15+ other comment lines) tripped this. Switched
every comment to ";", which parse_ini_file treats as a true inert
comment regardless of content — verified with isolated repros of
both prefixes under all three INI_SCANNER_* modes.
2. LDAP_BIND_DN's example value contained unquoted "=" and commas,
violating the file's own documented quoting rule and causing a
second, independent parse failure. Quoted it (and the two other
comma-bearing LDAP DN values) to match the rule.
config.php has zero fallback for a parse failure — it die()s
immediately — so either bug alone would have taken down every fresh
deployment that didn't hand-edit the example file's comments first.
Verified end-to-end: copied .env.example to a real .env file
unmodified and ran it through config.php's exact parse_ini_file +
quote-stripping logic; it now parses cleanly with all 23 keys
(including the 5 new ones) and LDAP_BIND_DN resolves to the correct
unquoted DN string.

- migrations/000_baseline.sql: full schema baseline captured from prod
(validated on a throwaway DB: 17 tables/17 FKs), so the schema is
reproducible for fresh installs / disaster recovery
- create_recurring_tickets cron: send the Matrix ticket-created
notification and invalidate the stats cache like the other create paths
- create_ticket_api.php + TicketController::create: invalidate the stats
cache on create/escalate/reopen so dashboard counts aren't stale
- scripts/cleanup_orphan_uploads.php: restored, made safe (24h mtime
grace, 9-digit-dir only, skips avatars/symlinks, matches the unique
filename column, --dry-run)
- cron/cleanup_audit_log.php: enforce the configured audit-log retention
(deleteOldLogs was implemented but never called)
- README: correct CSRF-rotation, hwmon dedup (no 24h window), SLA (no P3),
stats-cache callers, and the project structure/endpoint listing
- .env.example: document TRUSTED_PROXIES fail-open risk and .env quoting

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.

- Add helpers/NotificationHelper.php: shared Matrix webhook sender
that reads MATRIX_WEBHOOK_URL and MATRIX_NOTIFY_USERS from config
- Remove sendDiscordWebhook() from TicketController; call
NotificationHelper::sendTicketNotification() instead
- Replace 60-line Discord embed block in create_ticket_api.php
with a single NotificationHelper call
- config/config.php: DISCORD_WEBHOOK_URL → MATRIX_WEBHOOK_URL +
new MATRIX_NOTIFY_USERS key (comma-separated Matrix user IDs)
- .env.example: updated env var names and comments
Payload sent to hookshot includes notify_users array so the
JS transform can build proper @mention links for each user.
