Vulnerability from github – Published: 2026-01-07 12:31 – Updated: 2026-01-07 12:31

Details

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 ?

7.5 (High)


                  
                    CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N
