Incomplete Security Scanner Blocklist Enables Network-Based Code Execution

Description
IBM Langflow OSS 1.0.0 through 1.10.0 can allow attackers to execute arbitrary Python code with root privileges (UID=0) on the Langflow server by submitting components containing socket or urllib imports. This enables: (1) AWS credential theft via IMDSv1 SSRF with full IAM role permissions, (2) arbitrary file exfiltration from the container filesystem, and (3) lateral movement to internal services (PostgreSQL, Redis) within the Docker network. The scanner incorrectly returns "validated": true, providing a false security signal.
