CVE-2022-2456Public exploitNetwork attack vector

Unauthorized visibility changes via inconsistent numeric coercion

Published Aug 5, 2022 · Updated Aug 3, 2024

Incorrect authorization in GitLab CE/EE 15.0.4 and earlier, 15.1.0 through 15.1.3, and 15.2.0 allows remote authenticated users to change visibility. UpdateVisibilityLevel validates a coerced visibility value before the submitted string is later converted with to_i, so 20r compares as private but is saved as public. Maintainer access to a target project or group is required, and a successful request can make that private target public.
