Descriptions

Backdrop CMS 1.12.x before 1.12.8 and 1.13.x before 1.13.3 doesn't sufficiently filter output when displaying certain block labels created by administrators. An attacker could potentially craft a specialized label, then have an administrator execute scripting when administering a layout. (This issue is mitigated by the attacker needing permission to create custom blocks on the site, which is typically an administrative permission.)

CMS de Backdrop versiones 1.12.x anteriores a 1.12.8 y versiones 1.13.x anteriores a 1.13.3, no filtra suficiente la salida cuando se muestran ciertas etiquetas de bloque creadas por administradores. Un atacante podría diseñar una etiqueta especializada y luego hacer que un administrador ejecute scripting cuando se administre un diseño. (Este problema es mitigado por el atacante necesitando permiso para crear bloques personalizados en el sitio, que típicamente es un permiso administrativo).
