What it is
Ghost is often deployed as the public CMS behind a marketing site, docs site, or app blog. When the Content API dependency is in an affected range, a normal public surface can become a SQL injection risk against the backing database.
How it happens
CVE-2026-26980 is a SQL injection in Ghost's Content API that affects Ghost 3.24.0 through 6.19.0 and is fixed in 6.19.1. The Content API is the read-only API that themes and headless front ends use to fetch published posts, so it is reachable from the internet on almost every Ghost site. An injection there reaches the database behind the CMS.
What an attacker gets
A vulnerable Ghost Content API can expose or modify CMS data depending on deployment and database permissions. For AI-built SaaS sites, that may include unpublished content, author metadata, customer-facing pages, or credentials stored near the CMS runtime.

How to fix it
Upgrade `ghost` to 6.19.1 or newer, regenerate the active lockfile, deploy the patched runtime, and verify the running instance uses the fixed version. Review Content API logs and rotate nearby secrets if the vulnerable instance was publicly reachable.
