Description OSIDB Bzimport 2026-09-10 13:22:07 UTC
Renovate is a dependency update automation tool. When listing tags/digests for a container image, Renovate follows pagination links supplied by the remote registry in the HTTP Link header and attaches the registry credentials to the follow-up request without verifying that the pagination URL has the same origin as the original registry. A malicious or compromised container registry can therefore specify a Link header pointing to an attacker-controlled host and receive the credentials Renovate uses for that registry. Exploitation requires that the target has container (Docker) dependencies and is already interacting with the malicious or compromised registry. This is fixed in Renovate 44.11.2 (npm and renovate/renovate images), Mend Renovate CE/EE 15.4.0 and the mend-renovate-enterprise-edition Helm chart 10.4.0; the same-origin check can be disabled with RENOVATE_X_DOCKER_PAGINATION_ALLOW_CROSS_ORIGIN.
