CVE-2025-1278Network attack vector

Issue-title disclosure via group IP restriction bypass

Published May 9, 2025 · Updated May 9, 2025

Access control bypass in affected GitLab CE/EE releases allows remote attackers to read issue titles outside permitted IP ranges. GitLab has not disclosed the request path or missing authorization check that lets a request evade group IP-range enforcement. Reachability requires a group with IP restrictions and a request from outside its permitted ranges; the demonstrated consequence is disclosure of a restricted project issue title.
