Short explanation
The WP Compress – Instant Performance & Speed Optimization plugin for WordPress up to version 7.22.01 suffers from an authorization bypass vulnerability due to improper authorization verification. Unauthenticated attackers can link target sites to attacker-controlled accounts.
This security flaw enables unauthenticated individuals to execute privileged operations such as cache purging, file deletion, and altering plugin configurations.
What should be done?
- Monitor vendor advisories and plugin updates
- Apply updates promptly once official patches are released
The sources give limited detail on some technical conditions. Review the chain of evidence below before deciding how to act.
Chain of evidence and sources
WP Compress eklentisinin 7.22.01 ve önceki sürümleri yetkilendirme atlatma açığına karşı savunmasızdır.
Açık, saklanan anahtarın bulunmadığı taze kurulumlarda veya lite/free mod kurulumlarında etkilidir.
Show the technical text from the sources
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.
