CVE-2025-11877
No known patch is available for this vulnerability.
The affected plugin has been removed from the WordPress.org directory (reason: Security Issue), and no patched version is being distributed through the official directory. If you have the affected software installed, you should uninstall or replace it rather than wait for an update.
Description
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. CVE-2025-13471 appears to be a duplicate of this CVE.
