CVE-2026-13448: IBM Langflow OSS 1.0.0 through 1.10.1 Lanflow OSS contains an unauthenticated remote code execution vulnerability in the

IBM Langflow OSS (an open-source tool for building AI workflows) versions 1.0.0 through 1.10.1 have an unauthenticated remote code execution vulnerability (RCE, where attackers can run commands on the system without logging in) in a public endpoint. The vulnerability exists because the validate_public_flow_no_code_execution() function (a safety check) has an incomplete denylist (a list of things to block) that fails to block certain agent components like OpenDsStarAgent, CodeActAgentSmolagents, and CSVAgent from executing code.
