CVE-2024-30481Network attack vector

Subscriber-level unauthorized privileged action

Published Jun 9, 2024 · Updated Apr 28, 2026

Broken access control in JCH Optimize 4.0.0 and earlier allows remote authenticated users to perform an unspecified privileged action. Patchstack has not published the affected function, request parameter, or missing authorization check, so the exact wrong operation remains undisclosed. Subscriber-level access is required, and the published assessment limits the established consequence to integrity impact without confidentiality loss or service interruption.
