CVE-2019-12433Network attack vector

Authenticated permission bypass via internal project creation

Published Mar 10, 2020 · Updated Aug 4, 2024

Improper input validation in GitLab CE and EE 11.7 through 11.11 allows remote authenticated users to bypass private-group permissions. The project-creation path accepts Internal visibility for a project inside a Private group without enforcing the parent group's stricter visibility. A user able to create a group project can expose its repository to signed-in nonmembers rather than only private-group members.
