Detailsinfo

A vulnerability classified as critical was found in Red Hat Quay 3. This vulnerability affects an unknown code block of the component Clair. The manipulation with an unknown input leads to a server-side request forgery vulnerability. The CWE definition for the vulnerability is CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. As an impact it is known to affect confidentiality. CVE summarizes:

A flaw was found in Clair. The fetcher component makes outbound HTTP requests to attacker-supplied URIs from manifest layer descriptors without IP or scheme filtering. When PSK authentication is not configured (opt-in, not enforced by default), an unauthenticated attacker can submit a manifest with a URI pointing to internal services or cloud metadata endpoints. The SSRF is reflective for non-200 responses, leaking up to 256 bytes of error body content via CheckResponse error messages. Operator-managed Red Hat Quay deployments auto-configure PSK and are not exposed to the unauthenticated attack vector.

The advisory is shared for download at access.redhat.com. This vulnerability was named CVE-2026-10517 since 06/01/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $5k-$25k (estimation calculated on 06/01/2026).
