Users should monitor IBM's advisories for updates and apply patches once available. Until then, limit access to trusted authenticated users and consider additional security controls to reduce risk.

Description

IBM Langflow OSS 1.0.0 through 1.10.3 could allow a remote authenticated attacker to execute arbitrary code due to improper validation of Python code during AST-based security scanning.
