CVE-2026-29072 Details
Description
Discourse is an open-source discussion platform. Prior to versions 2026.3.0-latest.1, 2026.2.1, and 2026.1.2, users who do not belong to the allowed policy creation groups can create functional policy acceptance widgets in posts under the right conditions. Versions 2026.3.0-latest.1, 2026.2.1, and 2026.1.2 contain a patch. As a workaround, disable the discourse-policy plugin by disabling the `policy_enabled` site setting.
A vulnerability in Discourse prior to versions 2026.3.0-latest.1, 2026.2.1, and 2026.1.2 allows users not in the designated policy creation groups to create functional policy acceptance widgets in posts, under certain conditions. The issue arises from a missing permission check for policy creation. Exploitation of this vulnerability could lead to unauthorized policy acceptance actions being performed on behalf of the user.
Users can upgrade to Discourse versions 2026.3.0-latest.1, 2026.2.1, or 2026.1.2 to address this vulnerability. Alternatively, the Discourse policy plugin can be disabled by turning off the 'policy_enabled' site setting.
