Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: High: The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Subsequent System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade TryGhost Ghost to 6.11.0 or 5.130.6.

AI-suggested

European organizations should immediately upgrade affected Ghost CMS instances to versions 5.130.6 or 6.11.0 or later, where the SSRF vulnerability has been patched. In addition to patching, organizations should implement strict access controls on the Ghost Admin API, ensuring that only trusted staff users have access and that authentication tokens are securely managed and rotated regularly. Network segmentation should be enforced to limit the Ghost server's ability to reach sensitive internal services, reducing the impact of potential SSRF exploitation. Monitoring and logging of API usage and unusual outbound requests from the Ghost server can help detect exploitation attempts. Employing web application firewalls (WAFs) with SSRF detection rules may provide additional protection. Finally, conduct regular security audits and penetration tests focusing on SSRF and API abuse scenarios to identify and remediate similar issues proactively.

Description

Ghost is a Node.js content management system. In versions 5.38.0 through 5.130.5 and 6.0.0 through 6.10.3, a vulnerability in Ghost’s media inliner mechanism allows staff users in possession of a valid authentication token for the Ghost Admin API to exfiltrate data from internal systems via SSRF. This issue has been patched in versions 5.130.6 and 6.11.0.

Impact

For European organizations using affected versions of the Ghost CMS, this SSRF vulnerability poses a risk of internal data exposure and reconnaissance. Attackers with staff-level access could leverage this flaw to access internal services that are not directly exposed to the internet, such as internal APIs, cloud metadata endpoints, or backend databases. This could lead to leakage of sensitive configuration data, credentials, or other internal information that could facilitate further attacks or lateral movement within the network. The impact is particularly significant for organizations hosting Ghost CMS on cloud infrastructure or within segmented internal networks where SSRF can bypass network controls. While the vulnerability does not directly allow remote code execution or denial of service, the ability to exfiltrate internal data can compromise confidentiality and aid attackers in escalating privileges or pivoting to more critical assets. Given the requirement for valid staff credentials, the threat is heightened if credential theft or insider threats are present. The medium severity rating reflects the moderate risk, but the potential for sensitive internal data exposure warrants prompt remediation.
