Items resolved:
- #3 (HIGH): Move file uploads outside webroot to STORAGE_ROOT (/var/www/posterg/storage).
Uploads were previously stored in public/admin/actions/data/ which is web-accessible.
- #4 (HIGH): Align file paths and add media.php controller.
DB paths are now storage-relative (theses/YEAR/ID/file, covers/file).
New public/media.php serves files with path-traversal jail, MIME allow-list,
and proper caching headers. memoire.php and search.php updated to use /media.php?path=.
Also fixed: cover images were never recorded in thesis_files (broken INSERT).
- #5 (HIGH): RateLimit::getClientIdentifier() now uses REMOTE_ADDR only.
HTTP_X_FORWARDED_FOR and HTTP_CLIENT_IP are attacker-controlled headers that
allowed unlimited rate-limit bypass by rotating spoofed IPs.
- #6 (HIGH): Port public/admin/.htaccess security rules to nginx/posterg.conf.
Apache .htaccess directives are silently ignored by nginx; none were active.
CSP added to /admin/ location block, .log file denial added globally,
autoindex off made explicit. Documented in nginx/HTACCESS_TO_NGINX.md.
Supporting changes:
- config/bootstrap.php: add STORAGE_ROOT constant
- nginx/SECURITY_HEADERS.md: updated to reflect admin CSP and pending public CSP
- docs/TODO.SECURITY.md: items #3-6 moved to resolved; priority order updated
