CVE-2026-105650 · Severity: high · CVSS 8.1 · Published 2026-10-02

Ghost is a blogging platform that allows content creators to publish articles and newsletters. A vulnerability in how Ghost processes embedded media from external websites allows attackers to inject malicious scripts into posts. These scripts can run in the editor, on published pages, and in newsletter emails, potentially allowing attackers to steal administrator credentials and compromise staff accounts.

  ```


## 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.
