- Summary
- Discourse: Don't leak restricted tag group names via tag info
- Details
-
Discourse is an open-source discussion platform. From versions 2026.1.0-latest to before 2026.1.4, 2026.3.0-latest to before 2026.3.1, and 2026.4.0-latest to before 2026.4.1, DetailedTagSerializer#taggroupnames returned every tag group a tag belonged to without filtering against the requesting user's visibility. With SiteSetting.tagslistedbygroup enabled, anonymous and unprivileged users hitting TagsController#info (which is exempt from requireslogin) could read the names of tag groups restricted to specific user groups or non-visible categories. This issue has been patched in versions 2026.1.4, 2026.3.1, 2026.4.1, and 2026.5.0-latest.1.
