CVE-2026-12696
The wpForo Forum WordPress plugin before 3.1.2 does not sanitize and escape a user profile field before outputting it inside an HTML attribute on the public participant profile page, allowing users with a subscriber-level account to inject JavaScript that executes in the browser of any visitor who views the profile, including a logged-in administrator.
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.
