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.
