Description
GitLab has remediated an issue in GitLab CE/EE affecting all versions from 18.2 before 19.3.6, 19.4 before 19.4.3, and 19.5 before 19.5.1 that, under certain conditions, could have allowed an authenticated user with a read_api-scoped token to retrieve a project's incoming email address and create work items, bypassing the token's restrictions, due to insufficient scope enforcement on a GraphQL field.
