CyberRota Analysis
AI-GeneratedThe vulnerability in Discourse affects the discourse_templates endpoint, which improperly exposes hidden tag names due to insufficient filtering by the DiscourseTemplates::TemplatesSerializer. This flaw allows unauthorized users to access tags they should not be able to view, potentially leading to information disclosure. Organizations using affected versions should prioritize updating to versions 2026.1.6, 2026.5.2, 2026.6.1, or 2026.7.0 to mitigate this risk.

Original NVD Description
Discourse is an open-source discussion platform. Prior to 2026.1.6, 2026.5.2, 2026.6.1, and 2026.7.0, the discourse_templates endpoint exposed hidden tag names because DiscourseTemplates::TemplatesSerializer in plugins/discourse-templates/app/serializers/discourse_templates/templates_serializer.rb did not filter tags through the request Guardian. The serializer did not respect tag group permissions, allowing users to see tags they were not permitted to view. This issue is fixed in versions 2026.1.6, 2026.5.2, 2026.6.1, and 2026.7.0.
