Technical details

Ghost versions 2.5.0 through 6.63.x fail to properly sanitize oEmbed photo responses, allowing stored XSS via malicious image metadata. An attacker can host a malicious oEmbed endpoint that serves crafted photo responses; when a Ghost user embeds the URL, the untrusted scripts are stored in post content and execute in the editor, published site, and email newsletters. Exploitation requires user interaction (embedding the attacker's URL) but grants access to authenticated sessions.
