Summary
The WP Compress plugin for WordPress, in all versions up to and including 7.22.01, is affected, specifically fresh installations or lite/free installs that do not yet have an API key stored. An unauthenticated attacker could exploit this flaw to link the site to their own account, change plugin settings, and obtain the API key, giving them control over privileged functions such as cache purging and file deletion.
Read the original description
The WP Compress – Instant Performance & Speed Optimization plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 7.22.01. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to link the victim site to an attacker-controlled WP Compress account, overwrite plugin settings to an aggressive live-CDN preset, and gain the shared api_key that authenticates all nopriv HMAC-gated endpoints — enabling full control over cache purging, file deletion, opcode cache invalidation, and other privileged plugin operations. This vulnerability only affects fresh installations or lite/free-mode installs where no api_key is already stored, as the sole guard fails open when the stored key is absent.
