Registry credential disclosure via cross-origin pagination
Published Sep 10, 2026 · Updated Sep 10, 2026
Credential disclosure in Mend.io Renovate before 44.11.2 allows remote attackers to steal registry credentials via Docker pagination. The Docker registry tag and digest pagination handler follows a Link header to another origin and reattaches the original registry's credentials. Exposure requires container dependencies and interaction with a malicious or compromised registry, which can redirect the credentials to another host.
