CVE-2023-41318

Summary

CVE-2023-41318 is a vulnerability affecting matrix-media-repo, a media repository used in the Matrix chat ecosystem. In exploited versions, an attacker can upload malicious media containing scripted SVG content. Upon download, this media is served with `Content-Disposition: inline`, allowing the script to execute in the user's browser. The issue has been resolved in commits `77ec235` and `bf8abdd`, which are included in version 1.3.0. Matrix chat ecosystem operators should upgrade to version 1.3.0 immediately. As a temporary workaround for those unable to upgrade, it is recommended to override the `Content-Disposition` header returned by matrix-media-repo.
