IBM has released a security bulletin warning of critical vulnerabilities affecting Langflow OSS that could allow unauthenticated or authenticated attackers to execute arbitrary code and operating-system commands on the underlying server.

Langflow OSS is affected by two critical vulnerabilities that could enable arbitrary code or operating-system command execution. The first, CVE-2026-19286, may be exploited remotely without authentication through publicly accessible A2A flows, while the second, CVE-2026-19285, allows an authenticated user it inject malicious flow data and execute commands on the underlying server. Successful exploitation could result in sensitive data exposure, workflow manipulation, and complete server compromise. The vulnerabilities have Proof-of-Concept (PoC) publicly available.
