Langflow OSS is affected by arbitrary code execution in custom component validation and trusted code enforcement PUBLISHED

Description (CNA)

IBM Langflow OSS 1.0.0 through 1.10.3 does not properly validate the username field, allowing attackers to inject path traversal sequences and bypass containment checks.
