Does this matter?

Lower severity and a low EPSS score (0.18%). Track it; it rarely justifies an emergency change on its own.

Description

Omnispace Agora Project before 26.10.0 contains a stored cross-site scripting vulnerability that allows authenticated attackers to inject HTML/script markup by uploading a poll-response attachment with a malicious filename that bypasses the paramFilter sanitization applied to $_FILES. Attackers can submit a crafted filename that is stored and later rendered in components such as the dashboard controller (CtrlDashboard), executing arbitrary script in the browsers of users who view the affected page.
