The nonce check uses && (AND) instead of || (OR), which means providing any value for the security parameter causes the entire check to be skipped. This makes it possible for unauthenticated attackers to cancel arbitrary bookings by supplying a predictable booking ID."}], "lastModified": "2026-06-17T10:59:31.580", "sourceIdentifier": "security@wordfence.com"}
