Summary
Gitea repository ownership escalation by administrators
Details

Gitea's collaboration access-mode endpoint accepts the Owner access mode from an authenticated repository collaborator with Admin access. The collaborator can promote their effective permissions from Admin to Owner and then perform owner-only operations, including transferring the repository to their own account. This bypasses the intended boundary between repository administration and ownership.
