Overview
ghost is a publishing platform
Affected versions of this package are vulnerable to Arbitrary Code Injection via a vulnerability in the SVG handling of an image processing library bundled with Ghost. When a staff user (including a Contributor) creates a bookmark card pointing to an attacker-controlled website, the server fetches and processes attacker-supplied SVG content, resulting in arbitrary commands being executed on the Ghost server.
