Summary
Gitea's repository markup endpoint resolves same-repository pull request references without enforcing the viewer's Pull Requests permission. A member with only Wiki access to a private repository can submit a markup preview request and retrieve a private pull request's title and state icon despite lacking Issues and Pull Requests access. This exposes pull request metadata across repository unit permissions.

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.
