Go to dashboardLangflow runs user-supplied Python with exec() in its code validation path (validate_code, exec_globals), which gives remote code execution, as root in some deployments. ZDI rates it CVSS 9.8 with no authentication needed. A public PoC exists and CISA lists it as exploited. Affected: all versions up to and including 1.7.3. No fixed version is named in the advisories I read.

pip show langflow or docker image inspect to get the version; <= 1.7.3 is affected1.8.0 (github.com/langflow-ai/langflow/releases/tag/v1.8.0) is a later release, but I did not verify it fixes this CVEEach row is the first time that source carried this signal. The analyst’s rows are its own findings.
Langflow contains an inclusion of functionality from untrusted control sphere vulnerability that allows remote attackers to execute arbitrary code on affected installations.
