Advisory Weakness Curation

Remote command injection when using sendmail email transport ### 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 security@ghost.org
