Credential disclosure via cross-origin NuGet pagination
Published Sep 10, 2026 · Updated Sep 10, 2026
Credential disclosure in Renovate before 44.11.2 allows remote attackers to receive NuGet registry credentials through pagination. Renovate follows a registry-supplied next-page URL from the Link header without enforcing same-origin and attaches the configured registry credentials to that request. Exploitation requires a malicious or compromised NuGet registry, and the credentials are delivered to an additional attacker-chosen host.
