Title
User Activity Log <= 2.2 - Unauthenticated Limited Options Update via Failed Login
Summary
The User Activity Log plugin is vulnerable to a limited options update in versions up to, and including, 2.2. The failed-login handler 'ual_shook_wp_login_failed' lacks a capability check and writes failed usernames directly into update_option() calls. This makes it possible for unauthenticated attackers to push select site options from 0 to a non-zero value, allowing them to reopen registration or corrupt options like 'wp_user_roles', breaking wp-admin access.
Severity ?
