What is CVE-2026-32619?

Discourse, an open-source discussion platform, allowed users who lost access to certain topics to still interact with polls within those topics. Specifically, users could vote on polls or modify poll statuses, despite being removed from private category groups. This vulnerability did not expose any content, but it posed a risk to the integrity of poll states in contexts where users should not have had access. The issue has been addressed in versions 2026.1.3, 2026.2.2, and 2026.3.0.
