Summary
### Impact Sites using the `sendmail` transport as part of their `mail` config are vulnerable to remote command injection due to a [vulnerability](https://github.com/advisories/GHSA-48ww-j4fc-435p) in the `nodemailer` dependency. Ghost defaults to the `direct` transport so this is only exploitable if the `sendmail` transport is explicitly used. ### Patches Fixed in 4.15.0, all sites should upgrade as soon as possible. ### Workarounds * Use an alternative email transport as described in the [docs](https://ghost.org/docs/config/#mail). ### For more information If you have any questions or comments about this advisory: * email us at [email protected]
