Technical details

A Cross-Site Scripting (XSS) vulnerability exists in the WP Activity Log plugin for WordPress (versions 5.6.3.1 and earlier) due to improper neutralization of input during web page generation (CWE-79). The vulnerability can be triggered by a user with 'Subscriber' level privileges or higher, though the CVSS vector suggests it may be reachable without authentication under certain conditions (AV:N/PR:N). Successful exploitation requires a victim (typically an administrator) to interact with a malicious link or view a specific page within the WordPress dashboard. This allows the attacker to execute arbitrary JavaScript, potentially leading to session hijacking or unauthorized configuration changes. The issue is resolved in version 5.6.4.
