CVE-2019-13001Network attack vector

Unauthorized private snippet comments via missing permission check

Published Mar 10, 2020 · Updated Aug 4, 2024

Incorrect authorization in GitLab CE and EE 11.9 through 12.0.2 allows remote authenticated users to comment on private snippets. The snippet-note creation path persisted a note without correctly checking whether the commenter could access the private snippet. A low-privileged account is required, and the demonstrated impact is limited to unauthorized comment creation.
