Summary
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.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
The maintainers of go-gitea/gitea published their own advisory on GitHub. Reviewed sources take precedence over it.
