AI-suggested

Until an official fix is released, restrict user roles to trusted users only and monitor for suspicious activity related to the plugin's AJAX functions. Avoid granting Subscriber-level or higher access to untrusted users. Follow the vendor's updates closely for any forthcoming patches or official mitigations.

Description

The WP Compress – Instant Performance & Speed Optimization plugin for WordPress is vulnerable to unauthorized access, modification, and loss of data due to missing capability checks on its on its AJAX functions in all versions up to, and including, 6.30.15. This makes it possible for authenticated attackers, with Subscriber-level access and above, to compromise the site in various ways depending on the specific function exploited - for example, by retrieving sensitive settings and configuration details, or by altering and deleting them, thereby disclosing sensitive information, disrupting the plugin’s functionality, and potentially impacting overall site performance.
