Official Description
GitLab has remediated an issue in GitLab CE/EE affecting all versions from 17.1 before 18.10.7, 18.11 before 18.11.4, and 19.0 before 19.0.1 that under certain conditions could have allowed an authenticated user to cause denial of service due to insufficient validation.
Technical Analysis
CVE-2026-1402 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.
