Résumé

Discourse Vulnerable to Stored XSS via Shared AI Conversation Onebox

Description d'origine

La description telle que publiée par la source (souvent en anglais).

Discourse is an open-source discussion platform. Prior to versions 2026.3.0, 2026.2.1, and 2026.1.2, the onebox method in the SharedAiConversation model renders the conversation title directly into HTML without proper sanitization. Versions 2026.3.0, 2026.2.1, and 2026.1.2 contain a patch. As a workaround, tighten access by changing the ai_bot_public_sharing_allowed_groups site setting.
