Executive Summary

The Passster WordPress plugin before version 4.2.26 has a security flaw that allows unauthenticated users to bypass its protection mechanisms. This is done by manipulating URLs with specific parameters like 'elementor-preview=1' or 'lc_action_launch_editing=1', which tricks the plugin into granting access to protected pages.

Detection Guidance

Check if the Passster WordPress plugin version is below 4.2.26. Manually inspect URLs for suspicious parameters like 'elementor-preview=1' or 'lc_action_launch_editing=1' which may indicate exploitation attempts.

Impact Analysis

An attacker could exploit this to access restricted content on your WordPress site without authentication. This might include private pages, sensitive data, or admin areas if the plugin is used for access control. The impact depends on how Passster is configured on your site.

Mitigation Strategies

Update the Passster plugin to version 4.2.26 or later immediately. Remove any unauthorized access or changes made via the vulnerability and review server logs for signs of exploitation.
