Exploitation injects arbitrary system commands that are executed with the privileges of the containerised Flowise process, typically root.

Attackers can reach the target by sending a crafted HTTP request containing the overriding parameters; no additional code execution prerequisites are required beyond the standard service operation."}}}}, "created": "2026-04-27T22:30:14.283698+00:00", "updated": "2026-04-28T07:30:26.344753+00:00", "vendors": ["flowiseai", "flowiseai$PRODUCT$flowise"]}
