CVE-2026-119627: Gitea limited-visibility profile disclosure with public-only tokens

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.
