Summary

Gitea versions from 0 before 28.3.0 compute the contribution heatmap at GET /api/v1/users/{username}/heatmap with the token owner's repository access and ignore the public-only restriction of access tokens. A holder of a user's public-only token can read contribution counts and 15-minute time buckets from that user's activity in private repositories, though repository names and contents are not disclosed. The issue is classified under CWE-200. Public-only tokens now count only activity visible to anonymous users.

Description from the CNA

`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.
