GitLab has remediated an issue in GitLab EE affecting all versions from 15.6 before 18.6.6, 18.7 before 18.7.4, and 18.8 before 18.8.4 that could have allowed an authenticated user to cause Denial of Service by uploading a malicious file and repeatedly querying it through GraphQl.
Technical Analysis
CVE-2026-1387 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in availability disruption (denial of service), with a CVSS base score of 6.5.
