Gitea restricted-user activity and heatmap disclosure

4.3 Medium

Gitea's activity-feed and contribution-heatmap API handlers do not apply the profile visibility check for restricted accounts viewing Limited-visibility users. A restricted user can retrieve activity records and contribution timestamps that the corresponding profile routes deny. Exposed activity can include repository names, commit messages, and issue or pull request events associated with qualifying public-repository activity.
