What the vulnerability does

01Description

The Activity Log for WordPress plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the winter_activity_log_action() function in all versions up to, and including, 1.2.8. This makes it possible for authenticated attackers, with Subscriber-level access and above, to view potentially sensitive information (e.g., the password of a higher level user, such as an administrator) contained in the exposed log files.

Explanation of Vulnerability in Simple Terms

02Summary

The Activity Log for WordPress plugin through version 1.2.8 fails to properly check user permissions before allowing access to activity log data. A logged-in user with low privileges can read sensitive activity information they should not have access to. The plugin does not validate authorization on activity log endpoints, exposing confidential data to any authenticated user.
