CVE-2026-97674Network attack vectorHinoki check available

Authenticated OS command execution

Published Oct 6, 2026 · Updated Oct 6, 2026

Code injection in IBM Langflow OSS 1.0.0 through 1.12.2 allows remote authenticated users to execute OS commands through the server. IBM's published CVE record does not identify the affected function or explain how attacker-controlled input reaches command execution. Exploitation requires authenticated access to a network-reachable instance; the published assessment identifies confidentiality and integrity effects, but no availability impact.
