## Technical details

A code injection vulnerability (CWE-94) exists in the CUGA component's CodeAgent within IBM Langflow OSS. The flaw is located in the Python code execution path, where improper input validation allows for object graph introspection. An authenticated attacker can leverage this to recover restricted modules and bypass security validators, ultimately executing arbitrary commands within the server process. The vulnerability is reachable over the network with low privileges and has a high impact on confidentiality, integrity, and availability. Users should upgrade to version 1.10.1 to remediate the issue.
