Description
Docmost is open-source collaborative wiki and documentation software. In versions prior to 0.71.0, improper neutralization of attachment URLs in Docmost allows a low-privileged authenticated user to store a malicious `javascript:` URL inside an attachment node in page content. When another user views the page and activates the attachment link/icon, attacker-controlled JavaScript executes in the context of the Docmost origin. Version 0.71.0 patches the issue.
