Description OSIDB Bzimport 2026-09-10 13:23:07 UTC 
Renovate before 44.11.3 fails to validate Link header destinations when following GitLab server pagination, allowing malicious servers to redirect credential-bearing requests. Attackers controlling a compromised GitLab server can specify a Link header pointing to attacker-controlled infrastructure to exfiltrate authentication credentials.
