CVE-2026-7658

IBM Langflow OSS 1.0.0 through 1.10.3 does not properly validate the username field, allowing attackers to inject path traversal sequences and bypass containment checks. This enables multiple severe impacts, including arbitrary directory deletion, cross-tenant data destruction, and JWT signing key deletion leading to session invalidation.

Summary		(es) IBM Langflow OSS 1.0.0 hasta 1.10.3 no valida correctamente el campo de nombre de usuario, permitiendo a los atacantes inyectar secuencias de salto de ruta y eludir las comprobaciones de contención. Esto permite múltiples impactos graves, incluyendo la eliminación arbitraria de directorios, la destrucción de datos entre inquilinos y la eliminación de la clave de firma JWT, lo que lleva a la invalidación de la sesión.
