MEDIUM 4.9EPSS 0.35%

Does this matter?

Lower severity and a low EPSS score (0.35%). Track it; it rarely justifies an emergency change on its own.

Description

Ghost is a Node.js content management system. From 5.37.0 until 6.67.0, a crafted request to the external media inliner could cause excessive CPU usage, making the Ghost server unresponsive. Exploiting this requires Administrator access. This issue is fixed in version 6.67.0.
