Summary

Renovate before 44.11.3 fails to validate Link header destinations when following GitLab server pagination. A malicious GitLab server can specify a Link header pointing to attacker-controlled infrastructure, redirecting credential-bearing requests and exfiltrating authentication credentials.

Risk Assessment

An attacker controlling a compromised GitLab server can steal credentials used by Renovate to access repositories. Leaked credentials may enable unauthorized access to source code and organizational resources.

Recommendation

Upgrade Renovate to version 44.11.3 or later. Consider limiting trust in GitLab servers and rotating credentials used by Renovate.
