Summary

The Just Highlight plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Highlight Color' setting in all versions up to, and including, 1.0.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the plugin's settings page.

Risk Assessment

An attacker with administrator-level access can inject malicious scripts that execute in the browsers of other users visiting the plugin's settings page, potentially leading to session theft or unauthorized actions.

Recommendation

Update the Just Highlight plugin to the latest version that fixes this vulnerability. If updating is not possible, restrict access to the plugin's settings page to trusted users only.
