Summary

Gitea before 28.3.0 checks only that a signed-in viewer can see a limited-visibility owner on profile and feed routes, ignoring a token's public-only restriction (CWE-1220). A user with a public-only token, sent over HTTP Basic authentication, can read the profile and public activity of limited-visibility users and organizations. The disclosure reveals existence and profile metadata but grants no write access.

Description from the CNA

The web profile and RSS/Atom feed routes of users and organizations checked only whether a signed-in viewer could see a limited-visibility owner, without considering the `public-only` restriction of the personal access token used to authenticate. Any user holding a public-only token could send it over HTTP Basic authentication to read the profile and activity feed of limited-visibility users and organizations, which are hidden from anonymous visitors and refused on the equivalent API routes. The disclosure covers existence, profile metadata and public activity; it does not grant write access.
