Gitea's /api/v1/teams/{id} API routes do not correctly enforce the public-only access token restriction.
A public-only token is intended to limit API access to public repositories and public organizations. However, several team API routes continue to return private team repository metadata and private team activity feed entries when called with a public-only token.
The /api/v1/teams/{teamid} route group uses:
orgAssignment(false, true)
This loads ctx.Org.Team, but does not load ctx.Org.Organization.
The checkTokenPublicOnly middleware checks organization visibility through ctx.Org.Organization. When ctx.Org.Organization is nil, the organization visibility check silently passes.
In addition, the team repository handlers return repositories without applying repository-level public-only filtering:
repo_model.GetTeamRepositories(...)
convert.ToRepo(...)
They do not call:
ctx.TokenCanAccessRepo(repo)
The team activity feed handler also sets:
IncludePrivate: true
but does not apply:
opts.ApplyPublicOnly(ctx.PublicOnly)
Vulnerability is verified on latest gitea release (1.26.2) and nightly build.
Frist, create a public-only organization-scoped token for a user who is a member of a team in a private org with private repositories:
Use the returned token to request team repositories:

The team activity feed endpoint can be tested similarly:
