Descriptions

matrix-media-repo is a highly customizable multi-domain media repository for the Matrix chat ecosystem. In affected versions an attacker could upload a malicious piece of media to the media repo, which would then be served with `Content-Disposition: inline` upon download. This vulnerability could be leveraged to execute scripts embedded in SVG content. Commits `77ec235` and `bf8abdd` fix the issue and are included in the 1.3.0 release. Operators should upgrade to v1.3.0 as soon as possible. Operators unable to upgrade should override the `Content-Disposition` header returned by matrix-media-repo as a workaround.

Matrix-media-repo es un repositorio de medios multidominio altamente personalizable para el ecosistema de chat de Matrix. En las versiones afectadas, un atacante podría cargar un contenido malicioso en el repositorio de contenidos, que luego se entregaría con "Content-Disposition: inline" al descargarlo. Esta vulnerabilidad podría aprovecharse para ejecutar scripts incrustados en contenido SVG. Los commits `77ec235` y `bf8abdd` solucionan el problema y se incluyen en la versión 1.3.0. Los operadores deben actualizar a la versión 1.3.0 lo antes posible. Los operadores que no puedan actualizar deben anular el encabezado "Content-Disposition" devuelto por Matrix-media-repo como workaround.
