Detailsinfo

A vulnerability was found in MervinPraison PraisonAI up to 4.6.57. It has been declared as critical. This vulnerability affects an unknown code block of the component APIKeyAuthMiddleware/JWTAuthMiddleware. The manipulation with an unknown input leads to a improper authentication vulnerability. The CWE definition for the vulnerability is CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

PraisonAI is a multi-agent teams system. Prior to 4.6.58, recipe serve installs APIKeyAuthMiddleware or JWTAuthMiddleware when an operator selects api-key or JWT authentication, but each middleware forwards requests when PRAISONAI_API_KEY or PRAISONAI_JWT_SECRET and the corresponding recipe value are absent. Unauthenticated clients can then reach recipe execution, input, and output surfaces and may trigger connected tools despite the operator explicitly enabling authentication. This issue is fixed in 4.6.58.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-57127 since 06/24/2026. The exploitation appears to be easy. The attack can be initiated remotely.
