## Technical details

Langflow OSS contains multiple code injection vulnerabilities (CWE-94) allowing authenticated attackers to execute arbitrary code due to improper control of code generation and insufficient sanitization of user inputs in code execution components. An attacker with valid authentication can trigger code execution through eval/exec paths, OS command injection, and misconfigured code-execution components that bypass administrative restrictions. The vulnerability requires prior authentication but no user interaction.
