## Technical details

The plugin fails to consistently resolve the target user of update-user actions between authorization and execution stages in its front-end Forms module. This allows an unauthenticated visitor to bypass authentication guards protecting administrator accounts via a race condition or parameter tampering attack. An attacker can gain administrative access and a valid session token, provided two front-end form configurations with visitor-controlled targets are published.
