Access violation vulnerability in WP Compress – Instant Performance & Speed Optimization 6.30.15

The WP Compress plugin for WordPress has a security vulnerability that could lead to unauthorized access, changes, and loss of data. This is because the plugin does not have proper checks in place for its AJAX functions in all versions up to 6.30.15. This means that attackers who are logged in with Subscriber-level access or higher could potentially compromise the website by accessing sensitive information, altering or deleting it, and causing disruptions to the plugin and overall site performance.
