19 Dec 2019 — An issue was discovered in Backdrop CMS 1.13.x before 1.13.5 and 1.14.x before 1.14.2. It doesn't sufficiently filter output when displaying content type names in the content creation interface. An attacker could potentially craft a specialized content type name, then have an editor execute scripting when creating content, aka XSS. This vulnerability is mitigated by the fact that an attacker must have a role with the "Administer content types" permission.

08 Aug 2019 — In Backdrop CMS 1.12.x before 1.12.8 and 1.13.x before 1.13.3, some menu links within the administration bar may be crafted to execute JavaScript when the administrator is logged in and uses the search functionality. (This issue is mitigated by the attacker needing permissions to create administrative menu links, such as by creating a content type or layout. Such permissions are usually restricted to trusted or administrative users.)
