The User Activity Log WordPress plugin through 2.2 does not properly handle failed login attempts in some cases, allowing unauthenticated users to set arbitrary options to 1 (for example to enable User Registration when it has been turned off)
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.

This User Activity Log WordPress plugin before 1.6.7 retrieves client IP addresses from potentially untrusted headers, allowing an attacker to manipulate its value. This may be used to hide the source of malicious traffic.
The User Activity Log WordPress plugin before 1.6.6 lacks proper authorisation when exporting its activity logs, allowing any authenticated users, such as subscriber to perform such action and retrieve PII such as email addresses.
The User Activity Log WordPress plugin before 1.6.5 does not correctly sanitise and escape several parameters before using it in a SQL statement as part of its exportation feature, allowing unauthenticated attackers to conduct SQL injection attacks.
The User Activity Log WordPress plugin before 1.6.3 does not properly sanitise and escape the `txtsearch` parameter before using it in a SQL statement in some admin pages, leading to a SQL injection exploitable by high privilege users such as admin.
