CVE-2026-67961Public exploit

Local code execution via Invoke sandbox bypass

Published Aug 17, 2026 · Updated Aug 18, 2026

Code injection in O2OA 10.0.2 allows local users to execute arbitrary code through the Invoke JavaScript sandbox. GraalvmScriptingFactory.checkText() blocks only literal class-loading strings, while allowClass() exposes Java classes that constructed JavaScript can reach. A Manager or SystemManager account must create and run the malicious Invoke script; successful exploitation grants the O2OA server process's access.
