Name of the Vulnerable Software and Affected Versions: WP System Log WordPress plugin versions prior to 1.0.21

Description: The issue concerns the WP System Log WordPress plugin, which does not properly sanitise, validate, and escape the IP address from login requests before displaying it in the admin dashboard. This could allow an unauthenticated attacker to perform Cross-Site Scripting attacks against administrators viewing the logs.

Recommendations: For WP System Log WordPress plugin versions prior to 1.0.21, update to version 1.0.21 or later to resolve the issue. As a temporary workaround, consider restricting access to the admin dashboard to minimize the risk of exploitation.
