CDN credential disclosure via administrator request URLs

Published Jul 23, 2026 · Updated Jul 23, 2026

Information exposure in Regular Labs Cache Cleaner Pro 9.7.6 and earlier allows attackers to obtain CDN credentials via administrator request URLs. The extension places CDN provider credentials into URLs generated for administrator-side purge requests instead of keeping them out of the request target. The affected path requires the Pro edition and configured CDN credentials; the vendor has not disclosed which URL consumer can observe them.
