CVE-2022-31128Network attack vector

Restricted branch creation via missing permission check

Published Aug 1, 2022 · Updated Apr 23, 2025

Authorization bypass in Enalean Tuleap allows remote authenticated users to create Git branches despite repository restrictions. The POST git/:id/branches handler creates a branch without enforcing the repository's fine-grained branch-write permissions. Any authenticated user able to call the REST endpoint can add a branch to a repository whose rules should deny that operation.
