CVE-2026-75411Public exploitNetwork attack vector

Authenticated command execution via Groovy blacklist bypass

Published Aug 26, 2026 · Updated Aug 26, 2026

Code injection in JeecgBoot 3.9.2 AI Flow CodeNode allows remote authenticated users to execute arbitrary OS commands. SecurityCheck compares Groovy source against blacklisted call patterns, but string concatenation hides the exec method name and reflection invokes it after inspection. An administrator JWT is required to add the malicious flow; the resulting flow can then be triggered through the unauthenticated run endpoint.
