CVE-2026-57127Public exploitNetwork attack vectorHinoki check available

Unauthenticated recipe execution via fail-open middleware

Published Sep 14, 2026 · Updated Sep 14, 2026

Authentication bypass in PraisonAI through 4.6.48 allows remote attackers to invoke recipe execution without credentials. APIKeyAuthMiddleware and JWTAuthMiddleware call the downstream handler when both the recipe secret and corresponding environment variable are absent. Exploitation requires recipe authentication to be selected without a secret and grants access to recipe inputs, outputs, execution, and connected tools.
