When a user requests a rebase of a Renovate pull request using the rebase/retry checkbox, Renovate skips the configured minimumReleaseAge checks and updates the targeted dependency to its latest published version. Consequently, an attacker who publishes a malicious dependency version to a public package registry can have that untrusted version incorporated into an automated pull request and executed in Continuous Integration (CI) pipelines before the designated waiting period elapses. Exploitation requires user interaction, since a repository maintainer or collaborator must trigger the rebase, and the direct impact is limited to integrity, with no direct effect on confidentiality or availability. Red Hat rates this flaw as MODERATE, consistent with the upstream CVSS v3.1 score of 4.7. The fix for the Konflux mintmaker-renovate-image component is deferred because the impact is MODERATE with a CVSS score below 7.0; until a fixed image is shipped, the residual risk remains that a user-requested rebase can bypass the minimumReleaseAge protection and pull a dependency version newer than the configured release age into a pull request and CI environment.", "threat_severity": "Moderate"}
