Summary
Gitea's repository-side team-link API lets a repository administrator who is not an organization owner attach organization teams to a repository, even when RepoAdminChangeTeamAccess is disabled. The endpoint does not enforce the organization's restriction on repository administrators changing team access, so unauthorized changes to which teams receive repository access are possible. Gitea versions through 1.27.2 are affected (CWE-266, CWE-863).
