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: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable 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 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: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable 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 or the CVSS exploit maturity 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 craftcms cms to 5.8.22 or 4.16.18.

AI-suggested

European organizations should immediately upgrade Craft CMS to versions 4.16.18 or 5.8.22 or later to apply the official patches addressing this SSRF vulnerability. In addition, administrators should audit GraphQL permissions to restrict save_images_Asset mutation access only to trusted and necessary users. Review and tighten allowed file extensions for image uploads, disallowing non-image types such as .txt to prevent bypassing validation. Implement network segmentation and firewall rules to limit the CMS server's ability to make outbound requests to internal IP ranges and cloud metadata endpoints. Employ runtime application self-protection (RASP) or web application firewalls (WAF) with SSRF detection capabilities to monitor and block suspicious internal requests. Regularly scan and monitor logs for unusual GraphQL mutation usage or unexpected internal network access attempts. Finally, conduct security awareness training for developers and administrators on secure CMS configuration and patch management best practices.

Description

CVE-2026-25492 is a Server-Side Request Forgery (SSRF) vulnerability in Craft CMS versions 3.5.0 through 4.16.17 and 5.0.0-RC1 through 5.8.21. It arises from the save_images_Asset GraphQL mutation, which improperly validates hostnames and allows fetching internal URLs by resolving domain names to internal IP addresses.

Impact

For European organizations, this vulnerability poses a risk of unauthorized internal network access and sensitive data exposure, particularly in cloud-hosted environments using AWS. Attackers exploiting this SSRF flaw can access internal services that are otherwise inaccessible externally, potentially retrieving metadata credentials that enable lateral movement, privilege escalation, or data exfiltration. This can compromise confidentiality and integrity of critical systems and data. Organizations relying on Craft CMS for their websites or intranet portals may face service disruption or reputational damage if exploited. The medium CVSS score reflects moderate impact, but the ability to access cloud credentials elevates the risk in environments heavily dependent on cloud infrastructure. Given the widespread use of Craft CMS in Europe, especially in sectors like media, education, and government, the vulnerability could be leveraged for targeted attacks or espionage. The absence of known exploits in the wild suggests a window for proactive remediation before active exploitation occurs.
