Packages
Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
SVG images included in content imports were stored without sanitization. An attacker who convinced an Administrator to import a crafted file could host scripts on the site's domain, possibly resulting in compromise of staff users' admin sessions.
### Vulnerable versions
This vulnerability is present in Ghost from v4.0.0 up to v6.65.0.
### Patches
v6.67.0 contains a fix for this issue.
### How to update
For self-hosters using Docker, find [Docker's official Ghost image here](https://hub.docker.com/_/ghost). Updating a Docker-based Ghost instance [is documented here](https://docs.ghost.org/install/docker#updating-ghost).
