Description
Omnispace Agora Project before 26.10.0 contains a stored cross-site scripting vulnerability that allows authenticated users to post messages containing attacker-controlled iframes through the messenger's HTMLPurifier SafeIframe branch. Attackers can craft a message with a malicious iframe that is stored and automatically rendered to other channel members, enabling zero-click drive-by downloads and framed JavaScript execution in recipients' browsers.
