CVE-2026-7667

IBM Langflow OSS 1.0.0 through 1.10.0 allows an authenticated attacker to create a malicious flow pointing to an attacker-controlled URL that returns a specially crafted Content-Disposition header (e.g., filename="../../../target/path" ), enabling arbitrary file write operations with attacker-controlled content to any path accessible by the Langflow process.

Summary		(es) IBM Langflow OSS 1.0.0 hasta 1.10.0 permite a un atacante autenticado crear un flujo malicioso que apunta a una URL controlada por el atacante que devuelve un encabezado Content-Disposition especialmente diseñado (por ejemplo, filename=’.. / .. / .. / target/path’), lo que permite operaciones de escritura de archivos arbitrarias con contenido controlado por el atacante a cualquier ruta accesible por el proceso de Langflow.
