CVE-2026-67426
Full vulnerability record from the local CVENow database.
Description
Flyto2 Core is an execution kernel for automation and AI-agent workflows. Prior to 2.26.7, the standalone flyto-verification service in src/core/verification_service.py exposes unauthenticated POST /run on 0.0.0.0:8344 and uses client-supplied callback_url for an outbound POST with X-Internal-Key: $FLYTO_RUNNER_SECRET while bypassing target_allowed, allowing unauthenticated SSRF and runner secret exfiltration. This issue is fixed in version 2.26.7.

Antes de la versión 2.26.7, el servicio independiente flyto-verification en src/core/verification_service.py expone un POST /run no autenticado en 0.0.0.0:8344 y utiliza una callback_url proporcionada por el cliente para un POST saliente con X-Internal-Key: $FLYTO_RUNNER_SECRET mientras omite target_allowed, lo que permite SSRF no autenticado y la exfiltración del secreto del runner. Este problema se solucionó en la versión 2.26.7."
