CVE-2026-59190
grav-plugin-admin is an HTML user interface that provides a way to configure Grav and create and modify pages. In 1.10.52 and earlier, an authenticated attacker with admin.users permission can change the password of any user account, including the super administrator, by sending a direct POST request to /admin/user/{username}?task=save with data[password] because saveUser authorizes the caller's user-management permission but does not verify whether the caller may edit the target user. This issue is expected to be fixed in version 1.10.53.
No public exploitation has been reported so far. No distribution fix is listed yet; apply vendor mitigations and monitor.
Recommended action: Track your distribution's security tracker and apply the fix as soon as it ships.

Affected & fixed versions by distribution
Versions are the native distribution strings (backport-aware): RHEL/Debian/SUSE backport fixes, so compare with the distro version comparator (dpkg / rpm / vercmp), not the upstream version.
No affected package in the tracked watchlist yet (Debian, Ubuntu, Arch, SUSE, Red Hat...). Triage may still be pending.
