CVE-2024-58351Network attack vector

Unauthenticated code execution via unrestricted configuration overrides

Published Jun 20, 2026 · Updated Jun 20, 2026

Code injection in Flowise before 2.1.4 allows remote attackers to execute code via overrideConfig in web embeds or the Prediction API. The execution path accepts unrestricted configuration keys, applies them to the running Chainflow, and relies on vm2 to contain attacker-controlled behavior. The feature is enabled by default and requires no authentication; abuse is self-targeted but can escape the sandbox, crash the server, make server-side requests, alter prompts, and exfiltrate server data.
