Technical details

A stored cross-site scripting (XSS) vulnerability exists in Ghost's handling of oEmbed photo responses. When a user embeds a URL from an attacker-controlled website, untrusted scripts can be stored in post content without proper sanitization. These scripts execute in multiple contexts: the Ghost editor, published sites, and newsletter emails, potentially allowing session hijacking of administrative users.

Affected products
