Administrator lockout via unrestricted self-banning controls
Published Dec 29, 2021 · Updated Apr 30, 2025
Improper access control in ifme 5.0.0 through 7.32 allows remote authenticated users to deactivate their own administrator accounts. The reporting, profile, search, ally, and comment views expose report or ban paths for administrator accounts and the current account without excluding those targets. An administrator must invoke a self-targeting action; successful use disables that account and eliminates administrative access when it is the only administrator.
