- Add Content-Security-Policy to main nginx server block (was only on /admin/)
- Add Cross-Origin-Opener-Policy and Cross-Origin-Resource-Policy headers
- Add includeSubDomains to HSTS header
- Set HttpOnly, Secure, SameSite=Lax session cookie params on public pages
(AdminAuth already hardens the /admin session with SameSite=Strict)
- Update xamxam.conf.reference and SECURITY_HEADERS.md to match
- Add DuplicateThesisException (typed, carries existing thesis metadata)
- Add Database::findDuplicateThesis(): matches on year + author + normalised
title (exact, prefix, Levenshtein ≤10% of longer string)
- ThesisCreateController::submit() runs duplicate check before any DB write
and throws DuplicateThesisException on match
- AppLogger::logDuplicate() writes status=duplicate entries to the JSON-lines
log for audit purposes
- App::flash/consumeFlash extended to support 'warning' flash type
- admin/actions/formulaire.php: catches DuplicateThesisException, logs it,
flashes an HTML warning toast with a clickable link to the existing thesis,
and repopulates the form fields
- partage/index.php: same catch block; surfaces a plain-text flash-warning
banner on the student form with identifier, title, and year of the match;
form is repopulated via session
- toast.php: renders toast--warning variant
- admin.css: .toast--warning + link colour rules
- form.css: .flash-warning style for the partage form
Requirements:
- parametres.php toggle: 'restricted_files_enabled' enables/disables the feature
- Public TFE page: when enabled + access_type=Interne, hides files, shows French
restriction message + access request form (metadata/synopsis still visible)
- ERG emails (@erg.school / @erg.be): auto-approve, send 24h access link immediately
- External emails: show justification textarea, create pending request, notify admin
- Admin panel /admin/file-access.php: approve/reject requests with optional notes,
sends access email on approval (linked from admin nav with pending count badge)
Security:
- One-time 24h email tokens (used_at + is_valid=0 on first click)
- Token redeemed via POST /validate-access (GET shows confirmation page only)
- Long-lived 30-day browser session in file_access_sessions table
- Cookie: HttpOnly + Secure + SameSite=Strict
- CSRF on all mutations, rate limiting on request submission
- Audit trail: IP, UA, event, timestamp in file_access_audit
Bug fixes:
- admin/file-access.php: $vars never extract()ed → page was blank
- Template had self-contained head/footer includes (double-include)
- Admin approval URL used $requestId instead of $request['thesis_id']
- App::boot() now starts session so CSRF token works on public pages
- Dispatcher routes /validate-access and /request-access through front controller
