Discourse prevents hidden profile data leak via user onebox (CVE-2026-32099)

Summary

Discourse prevents hidden profile data leak via user onebox

Original description

The description as published by the source.

Discourse is an open-source discussion platform. Prior to versions 2026.3.0, 2026.2.1, and 2026.1.2, when a user has hide_profile enabled, their bio, location, and website were still exposed through the user onebox preview. An authenticated user could request a onebox for a hidden user's profile URL and receive their hidden profile fields (bio, location, website) in the response. Versions 2026.3.0, 2026.2.1, and 2026.1.2 contain a patch. No known workarounds are available.
