Security Bulletin: Langflow OSS Authenticated Remote Code Execution (RCE) vulnerability exists in the validate_code function

Summary Langflow OSS contains a code injection vulnerability in its code validation endpoint. The endpoint executed submitted function definitions during validation, allowing decorator and default-argument expressions to run. An attacker with access to the endpoint could execute arbitrary command...

Langflow AI Code Validation Authenticated Remote Code Execution

Langflow versions 1.0.0 through 1.10.0 are susceptible to authenticated remote code execution due to improper validation of code in the /api/v1/validate/code endpoint. Arbitrary code is executed under the context of the backend Langflow process. This module requires Metasploit:...
