CVE-2026-31959 (opens in a new tab)How to fix?
Upgrade github.com/anchore/quill/quill/notary to version 0.7.1 or higher.
Overview
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via unvalidated URL from Apple notarization log retrieval due to a lack of validation on URLs provided in API responses. An attacker can cause the client to send HTTP or HTTPS requests to arbitrary or internal network destinations by tampering with the API response to supply a malicious URL. This could result in the exfiltration of sensitive data such as cloud provider credentials or internal service responses.
Note: This is only exploitable if the environment allows modification of notarization API responses, such as through TLS-intercepting proxies, compromised certificate authorities, or other trust boundary violations.
