CVE-2026-42785Public exploitNetwork attack vector

Authenticated code execution via unrestricted BeanShell evaluation

Published May 26, 2026 · Updated May 26, 2026

Code injection in OpenKM Community Edition 6.3.12 and Professional Edition 7.1.47 allows remote authenticated users to execute OS commands. The /admin/Scripting endpoint passes script content submitted with action=Evaluate directly to the BeanShell interpreter without sandboxing, command filtering, or execution constraints. Administrator access and a valid CSRF token are required, after which the code runs with the OpenKM application server's operating-system privileges.
