Title
Gitea private pull request title disclosure through markup
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.
Severity
