CVE-2025-67989 identifies a Server-Side Request Forgery (SSRF) vulnerability in LMPixels Kerge, a content management system widely used for building websites. SSRF vulnerabilities occur when an attacker can manipulate server-side code to make HTTP requests to arbitrary domains or IP addresses, often bypassing firewall restrictions and accessing internal network resources. In this case, versions of Kerge up to and including 4.1.3 are affected. The vulnerability allows attackers to coerce the server into sending crafted requests, which can lead to unauthorized access to internal services, sensitive data leakage, or pivoting deeper into the network. Although no public exploits have been reported yet, the nature of SSRF makes it a critical vector for attackers to bypass perimeter defenses. The lack of a CVSS score indicates the need for further analysis, but SSRF vulnerabilities typically impact confidentiality and integrity significantly. The vulnerability does not require authentication or user interaction, increasing its risk profile. The absence of patch links suggests that a fix may not yet be publicly available, emphasizing the importance of interim mitigations. Organizations using Kerge should audit their deployments, monitor outbound traffic, and apply network segmentation to reduce exposure. Given the widespread use of CMS platforms in Europe, this vulnerability could have broad implications if exploited.

For European organizations, exploitation of this SSRF vulnerability could lead to unauthorized internal network reconnaissance, data exfiltration, and potential lateral movement within corporate networks. Confidentiality is at risk as attackers might access internal APIs, databases, or cloud metadata services that are not intended to be publicly accessible. Integrity could be compromised if attackers leverage SSRF to interact with internal services that modify data or configurations. Availability impact is generally lower but could occur if SSRF is used to trigger denial-of-service conditions on internal resources. The ease of exploitation without authentication or user interaction increases the threat level, especially for public-facing Kerge installations. Organizations in sectors with sensitive data, such as finance, healthcare, and government, are particularly vulnerable. The lack of known exploits provides a window for proactive defense, but the potential for rapid weaponization remains. Failure to mitigate could result in significant operational disruption, data breaches, and regulatory penalties under GDPR for mishandling personal data.

1. Immediately restrict and monitor outbound HTTP/HTTPS requests from Kerge servers to only trusted destinations using firewall rules or proxy configurations. 2. Implement network segmentation to isolate web servers running Kerge from sensitive internal systems and APIs. 3. Conduct thorough code reviews and input validation on any functionality that processes URLs or external resource requests within Kerge. 4. Deploy web application firewalls (WAFs) with custom rules to detect and block suspicious SSRF patterns. 5. Monitor logs for unusual outbound request patterns or unexpected internal resource access attempts. 6. Stay in close contact with LMPixels for official patches and apply updates promptly once available. 7. Consider temporary disabling or limiting features that allow user-supplied URLs until a patch is released. 8. Educate development and operations teams about SSRF risks and detection techniques. 9. Use vulnerability scanning tools to identify SSRF exposures in the environment. 10. Prepare incident response plans specifically addressing SSRF exploitation scenarios.
