Discourse's Fail-Open Access Control in Data Explorer Plugin… (CVE-2026-28218)

Summary

Discourse's Fail-Open Access Control in Data Explorer Plugin Allows Unauthorized SQL Query Execution

Original description

The description as published by the source.

Discourse is an open source discussion platform. Prior to versions 2025.12.2, 2026.1.1, and 2026.2.0, fail-open access control in Data Explorer plugin allows any authenticated user to execute SQL queries that have no explicit group assignments, including built-in system queries. Versions 2025.12.2, 2026.1.1, and 2026.2.0 patch the issue. As a workaround, either explicitly set group permissions on each Data Explorer query that doesn't have permissions, or disable discourse-data-explorer plugin.
