Description

An XSS issue was discovered in the Link iframe formatter module before 1.x-1.1.1 for Backdrop CMS. It doesn't sufficiently sanitize input before displaying results to the screen. This vulnerability is mitigated by the fact that an attacker must have the ability to create content containing an iFrame field.
