Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-863.

Summary

Gitea versions from 1.27.0 through 28.0.0 are affected when FORCE_PRIVATE is set to true. The post-receive hook applies the repo.private=false push option to an empty repository created by push, bypassing the policy (CWE-863). An authenticated user with low privileges who can create repositories can make the new repository public against the instance policy.

Description from the CNA

With `[repository] FORCE_PRIVATE = true`, Gitea creates new repositories as private, but the post-receive hook still applied the `repo.private=false` push option to an empty repository created by push. Any user who can create repositories could make their new repository public in violation of the instance policy. The default configuration is not affected.
