घोस्ट में एक्सटर्नल मीडिया इनलाइनर के माध्यम से SSRF

An attacker exploiting this SSRF vulnerability could leverage a staff user's authentication token to make requests to internal resources that are otherwise inaccessible from the outside world. This could include accessing sensitive data stored on internal servers, querying internal APIs, or even interacting with other internal services. The potential impact ranges from information disclosure to potential escalation of privileges depending on the internal resources accessible via the SSRF. While the CVSS score is LOW, the ability to bypass internal network segmentation and access sensitive data makes this a significant concern, especially in environments with complex internal architectures.

Organizations utilizing Ghost CMS for their blogging or content management needs are at risk, particularly those with staff users who have access to the Ghost Admin API. Deployments with complex internal network architectures and sensitive data stored on internal servers are at higher risk, as the SSRF vulnerability could be used to bypass network segmentation and access this data.

• nodejs / server:

journalctl -u ghost | grep -i "ssrf"

• nodejs / server:

ps aux | grep -i "ghost" | grep -i "inliner"

• generic web: Use curl to probe internal endpoints accessible from the Ghost CMS server. Look for unexpected responses or data leakage.

curl -v http://<internal_ip>/<sensitive_endpoint>

The primary mitigation for CVE-2026-22597 is to upgrade Ghost CMS to version 6.11.0 or later, which includes the necessary fix. If upgrading immediately is not feasible, consider restricting the network access of the Ghost CMS server to only the necessary external resources. Implement strict access controls for the Ghost Admin API, limiting the privileges of staff users and regularly auditing their access. Monitor Ghost CMS logs for unusual outbound requests that could indicate exploitation attempts. While a WAF might offer some protection, it's unlikely to be sufficient without specific rules tailored to SSRF patterns within the Ghost CMS media inliner functionality.
