Technical description

`GET /api/v1/users/{username}/heatmap` computed the contribution heatmap with the repository access of the token owner and ignored the public-only restriction of the access token, unlike the activity feed endpoints. A holder of a user's public-only token could read contribution counts and their 15-minute time buckets that stem from that user's activity in private repositories. Repository names and contents were not disclosed. For public-only tokens the heatmap now only counts activity visible to anonymous users.

——0The OAuth2 userinfo endpoint (`/login/oauth/userinfo`) decided whether to limit the `groups` claim to public organizations by re-parsing the `Authorization` header as an OAuth2 access token instead of using the scope of the credential that authenticated the request. When a public-only OAuth2 token was sent as a query parameter or form field, or a public-only personal access token was used, that scope came back empty and the claim listed the token owner's private organizations, teams and concealed memberships. The disclosure is limited to the owner's organization and team names and memberships; no repository content is exposed. The endpoint now uses the scope of the authenticating token.4h CVE-2026-117649—

——0The issue timeline API and the web issue page hid cross-reference events that point at issues the reader cannot access, but not "dependency added" and "dependency removed" events. When a readable issue had been linked as a dependency to an issue in a repository the reader cannot access, for example a private repository, any reader of the first issue, including anonymous users of a public repository, received the linked issue's current title, body, state, labels, poster and attachment names through the API, and its repository, number and title on the web page. Creating the link requires access to both issues; comments and attachment downloads of the linked issue stayed protected. Dependency events are now filtered with the same read permission check; a related exposure of unlinked attachment metadata through hidden dependency placeholders was already fixed in 28.2.0.4h CVE-2026-112887—

——0Gitea Actions task tokens authenticate to the REST API as a shared system user with a negative ID, which repository, organization, project and key filters treated as having no owner restriction, and the token carried no API scope to restrict user-scoped routes. A user who can run a workflow could use the job's token with `GET /api/v1/user/repos` to list every repository on the instance, including private repositories of other users and organizations, with their metadata. Repository contents remained protected by per-repository permission checks. System users now own nothing, and `/api/v1/user` routes other than `GET /api/v1/user` accept only individual and bot accounts.4h CVE-2026-1201925.3 MED
