Detailsinfo

A vulnerability, which was classified as critical, was found in ai-inference-server (the affected version unknown). Affected is an unknown part of the file /invocations of the component API Inference Endpoint. The manipulation with an unknown input leads to a improper authentication vulnerability. CWE is classifying the issue as CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

A flaw was found in the authentication enforcement mechanism of a model inference API in ai-inference-server. All /v1/* endpoints are expected to enforce API key validation. However, the POST /invocations endpoint failed to do so, resulting in an authentication bypass. This vulnerability allows unauthorized users to access the same inference features available on protected endpoints, potentially exposing sensitive functionality or allowing unintended access to backend resources.

The advisory is shared for download at bugzilla.redhat.com. This vulnerability is traded as CVE-2025-6920 since 06/30/2025. The exploitability is told to be easy. The exploitation doesn't require any form of authentication. There are known technical details, but no exploit is available.
