CWE
  • CWE-200 - Exposure of Sensitive Information to an Unauthorized Actor
Summary
Gitea uses inconsistent repository visibility predicates, and the condition used by some repository-listing endpoints admits repositories whose owners are hidden from the viewer. Those listings disclose repository metadata even though direct routes correctly deny access with a 404 response. The issue exposes repository existence and listing information across the intended owner-visibility boundary.
