CVE-2026-54188Network attack vector

Unauthenticated script execution via unsanitized form status

Published Jun 17, 2026 · Updated Jun 17, 2026

Cross-site scripting in Crocoblock JetEngine 3.8.10 and earlier allows remote attackers to execute script via a crafted form status parameter. The legacy forms module reflects the status-related query parameter into page output without sufficient sanitization, allowing attacker-controlled markup to enter the rendered response. Exploitation requires an unauthenticated request and user interaction, and successful script execution acts with the affected visitor's browser privileges.
