CVE-2026-10517: 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 exploitability of CVE-2026-10517 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
With low attack complexity and no required privileges, CVE-2026-10517 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2026-10517, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2026-10517, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
