NVD description

Rocket.Chat in versions before 8.8.0, 8.7.1, 8.6.2, 8.5.3, 8.4.6, 8.3.8, 8.2.8, 8.1.8, and 7.10.15 has a REST API endpoint POST /api/v1/livechat/visitor that accepts an unauthenticated, unsanitized name field for Livechat visitors. This name is stored raw and later rendered via dangerouslySetInnerHTML in the Omnichannel Queue side panel (InquireSidePanelItem.tsx), injecting a real, clickable HTML link - pointing to any attacker-controlled domain, with arbitrary social-engineering text - into the DOM of any agent viewing the queue.
