- lib/AdminAuth.php: new class with requireLogin(), login(), logout(),
isAuthenticated(); starts session with hardened cookie params
(HttpOnly, SameSite=Strict, Secure, Path=/admin) — also resolves
item #8 (session cookie hardening)
- requireLogin() auto-authenticates from nginx Basic Auth credentials
($_SERVER['PHP_AUTH_PW']) so the user only sees one browser prompt;
falls back to /admin/login.php if the proxy is absent/misconfigured
- config/admin_credentials.php: gitignored credential store; define
ADMIN_PASSWORD_HASH with a bcrypt hash to enable PHP auth
- config/admin_credentials.example.php: template for the above
- config/bootstrap.php: auto-loads admin_credentials.php if present
- .gitignore: exclude config/admin_credentials.php
- public/admin/login.php: fallback login form (shown only when nginx
Basic Auth is bypassed / proxy absent)
- public/admin/logout.php: session destruction + redirect to login
- All 7 admin PHP files: replace session_start() with
AdminAuth::requireLogin() (defence-in-depth behind nginx Basic Auth)
- public/admin/inc/head.php: Déconnexion button when ADMIN_PASSWORD_HASH
is defined
- nginx/PHP_AUTH_LAYER.md: documents dual-auth architecture, UX flow,
and setup instructions
- docs/TODO.SECURITY.md: items #2 and #8 moved to Resolved; priority
order updated (all CRITICAL done)
