CVE-2026-66613Network attack vector

Unauthenticated remote code execution

Published Aug 19, 2026 · Updated Aug 20, 2026

Code injection in Crocoblock JetEngine before 3.8.14.1 allows remote attackers to execute arbitrary code via unspecified vectors. Patchstack mapped the flaw to CWE-1336, indicating improper neutralization of special elements in a template engine, but the public record does not disclose the vulnerable template sink or the exact untrusted input path that reaches execution. The published CVSS vector makes the issue network-reachable and unauthenticated, so exposed WordPress sites running JetEngine 3.8.14 and earlier should treat it as potential full site compromise within the web server context.
