api/bootstrap.php's centralized CSRF handling echoes
CsrfMiddleware::getToken() on a 403 rejection specifically so
lt.api's client-side resync (assets/js/base.js) can recover once
window.CSRF_TOKEN goes stale (token expiry, or a write in another tab
rotating the shared session-scoped token). 12 endpoints duplicate
CsrfMiddleware::validateToken() inline instead of routing through
bootstrap.php, and their 403 body omitted csrf_token entirely —
custom_fields.php, clone_ticket.php, delete_comment.php,
delete_attachment.php, bulk_operation.php, generate_api_key.php,
manage_templates.php, manage_recurring.php, revoke_api_key.php,
manage_workflows.php, ticket_dependencies.php, and
upload_attachment.php.
Once a client's token drifted out of sync, the next write to any of
these 12 endpoints returned a 403 with no way to self-heal — every
subsequent write to any endpoint kept failing until a manual reload,
since the resync mechanism was only wired up on a minority of the
app's write surface. Took the minimal fix the issue names as
sufficient (add 'csrf_token' => CsrfMiddleware::getToken() to each
rejection body) rather than restructuring all 12 through bootstrap.php,
to avoid behavioral risk from rewiring each endpoint's differing
auth/bootstrapping. generate_api_key.php and revoke_api_key.php threw
a generic Exception for this case (swallowed into a plain error-message
response with no room for extra fields), so those two now short-circuit
with a direct JSON response instead, matching the other 10.
Verified end-to-end against real running endpoints with a real
session and real MariaDB: sent a wrong CSRF token to one endpoint of
each response shape (plain json_encode, ResponseHelper::error, and the
formerly exception-based path) and confirmed all three now return the
current valid csrf_token in the 403 body.

assign_ticket.php: preserve string ticket ID (ctype_digit validation)
instead of (int) cast for consistent audit logging and URL generation.
delete_attachment.php: use string ticket_id from DB for the upload
directory path — (int) cast was stripping leading zeros, causing
the wrong path (/uploads/123456/) instead of /uploads/000123456/.
Also pass raw string to getTicketById() to let TicketModel handle
type coercion.

- delete_attachment.php: add realpath() path traversal check before
unlink() — mirrors the defense-in-depth already in download_attachment.php;
also cast ticket_id to int when building the path
- manage_templates.php: add input validation to POST and PUT handlers:
required field checks, max length caps (name 100, title 255, desc 64KB),
allowlist validation for category/type, priority clamped to 1-5

- delete_attachment.php: check canUserAccessTicket() before allowing deletion; return 404 (not 403) for inaccessible tickets to prevent existence leakage
- upload_attachment.php: verify ticket access on both GET (list) and POST (upload) before processing
- update_ticket.php: pass currentUser to controller; add canUserAccessTicket() check before permission check; return 404 for inaccessible tickets instead of leaking existence via 403
