Summary

Omnispace Agora Project before 26.10.0 contains a stored cross-site scripting flaw (CWE-79). The link address field is echoed into an onclick attribute without neutralizing quotes, so a crafted value can break out of the attribute. An authenticated user can store such a payload through the Links module, and it runs in the browser of any user who views the links list, enabling session hijacking or further client-side compromise.
