Official description

Plane is an open-source project management tool. Prior to 1.4.0, the plane comments fail to sanitize unsafe URL schemes stored in comment_html. A project member can store a crafted link in a comment, and attacker-controlled script executes in the browser context of another user who selects the link. This issue is fixed in version 1.4.0.
