Sources and claim methodology

Upstream source description

Omnispace Agora Project before 26.10.0 contains a stored cross-site scripting vulnerability that allows authenticated users to inject malicious scripts by submitting an unsanitized link address (adress) field that is echoed into an onclick event-handler attribute without neutralizing quotes. Attackers can store a crafted payload through the Links module that executes in the browser of any user viewing the links list, enabling session hijacking or further client-side compromise.
