Deeper analysisAI
CVE-2026-1069 is a denial-of-service vulnerability in GitLab Community Edition (CE) and Enterprise Edition (EE), affecting all versions from 18.9 prior to 18.9.2. The issue stems from uncontrolled recursion (CWE-674) triggered by specially crafted GraphQL requests under certain circumstances, allowing resource exhaustion. It carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) and was published on 2026-03-11.
An unauthenticated attacker can exploit this vulnerability remotely with low complexity by sending malicious GraphQL queries to a vulnerable GitLab instance. Successful exploitation results in denial of service through excessive resource consumption, potentially disrupting service availability without impacting confidentiality or integrity.
GitLab remediated the issue in version 18.9.2, as detailed in their patch release notes. Additional details are available in the associated GitLab work item and HackerOne disclosure report. Security practitioners should upgrade to 18.9.2 or later to mitigate the risk.
