Discourse missing permission check for policy creation in discourse-policy

Assigner: GitHub_M
Reserved: 03.03.2026 Published: 19.03.2026 Updated: 19.03.2026

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.
