CVE-2025-11246
Description
GitLab has remediated an issue in GitLab CE/EE affecting all versions from 15.4 before 18.5.5, 18.6 before 18.6.3, and 18.7 before 18.7.1 that could have allowed an authenticated user with specific permissions to remove all project runners from unrelated projects by manipulating GraphQL runner associations.
Summary dbcve.org
This is an authorization bypass vulnerability in GitLab's GraphQL API where an authenticated user with specific (likely non-admin) permissions could remove project runners from unrelated projects by manipulating GraphQL runner associations. The issue stems from insufficient access control checks when handling runner associations across different projects.
Mitigation
Upgrade GitLab to version 18.5.5, 18.6.3, 18.7.1 or later. As a compensating control, audit runner configurations and restrict GraphQL API access until patches are applied.
