  "summary": "Ghost versions 4.22.0 through 6.64.x can retain uploaded SVG content without adequate sanitization when it is handled as a thumbnail or given a non-SVG extension. A staff user, including a Contributor, could use this to run browser-side code under the site's origin and potentially compromise other staff sessions.",
