Authorization bypass via GraphQL mutations through GitLab GLQL API endpoint
GitLab CE/EE contains an authorization issue affecting versions 18.6 before 18.6.6, 18.7 before 18.7.4, and 18.8 before 18.8.4 where, under certain conditions, an authenticated user could perform unauthorized operations by submitting GraphQL mutations through the GLQL API endpoint. This is effectively an authorization bypass in the GLQL/GraphQL mutation handling path that allows actions beyond the attacker’s intended permissions.
