Unauthenticated code execution via undisclosed command handling

Published Oct 7, 2026 · Updated Oct 7, 2026

OS command injection in IBM Langflow OSS 1.0.0 through 1.12.2 allows remote attackers to execute code through a network request. IBM has not published the affected endpoint or the operation that passes attacker-controlled input into an OS command. IBM's assessment requires neither authentication nor user interaction; the resulting code runs in the context of the Langflow service.
