Cross-Site Request Forgery (CSRF) vulnerability in GTmetrix GTmetrix for WordPress plugin <= 0.4.7 versions.

A command injection vulnerability exists in RTS VLink Virtual Matrix Software Versions v5 (< 5.7.6) and v6 (< 6.5.0) that allows an attacker to perform arbitrary code execution via the admin web interface.

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.
