Description
Ghost is a Node.js content management system. From 4.9.0 until 6.54.1, an input validation issue allowed any staff user to create a post with content in feature_image_caption that could be used to hijack another staff user's Ghost Admin session, resulting in privilege escalation. This issue is fixed in 6.54.1.
