Description

Discourse is an open source discussion platform. Prior to versions 2025.12.2, 2026.1.1, and 2026.2.0, SQL injection in PM tag filtering (`list_private_messages_tag`) allows bypassing tag filter conditions, potentially disclosing unauthorized private message metadata. Versions 2025.12.2, 2026.1.1, and 2026.2.0 patch the issue. No known workarounds are available.

Affected configurations

• discourse discourse (< 2025.12.2) • discourse discourse (>= 2026.1.0 < 2026.1.1) • discourse discourse 2026.2.0
