Harden gallery authentication and authorization, consolidate gallery workflows, and prevent token-bearing URLs from leaking through nginx request error logs.
- maintenance mode classified paths case-sensitively while Express routes
case-insensitively, so /API/... walked past the gate
- the general rate limiter skipped anyone holding any verified JWT; a
gallery token is minted for free on password-less galleries and slideshow
links, so that was an unlimited budget for every /api route. Only admin
sessions skip now
- ?admin_preview=1 trusted a verified signature alone; it now applies the
same revocation, restore-cutoff, deactivation and password-change checks
adminAuth does, and reveal-mode reads the verified flag instead of
re-decoding the token
- the 50mb JSON limit is scoped to /api/admin and /api/v1; everything else
gets 2mb, so an unauthenticated body can no longer stall JSON.parse
- the CSRF Content-Type gate accepted multipart from any origin; cross-site
form posts are now rejected via Sec-Fetch-Site / Origin, with a Host match
fallback for same-origin installs that leave FRONTEND_URL unset
