CVE-2025-67989 is a Server-Side Request Forgery (SSRF) vulnerability found in LMPixels Kerge, a web content management system or related product, affecting all versions up to 4.1.3. SSRF vulnerabilities occur when an attacker can manipulate a server to send HTTP requests to arbitrary destinations, often internal or protected network resources that are otherwise inaccessible externally. In this case, the vulnerability does not require authentication (PR:N) but does require user interaction (UI:R), such as clicking a crafted link or submitting a malicious request. The attacker can leverage this flaw to access internal services, potentially bypassing firewall restrictions, and gather sensitive information or perform further attacks like port scanning or exploiting other internal vulnerabilities. The CVSS vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required, user interaction required, unchanged scope (S:U), and impacts on confidentiality and integrity but not availability (C:L/I:L/A:N). No patches or known exploits are currently available, indicating the vulnerability is newly disclosed. The lack of CWE identifiers suggests limited public technical details, but the nature of SSRF is well understood. Organizations using Kerge should assess their exposure, especially if their deployments allow outbound HTTP requests from the server or have sensitive internal services accessible only internally. Monitoring and restricting server outbound requests and validating user inputs are critical defenses.

For European organizations, this SSRF vulnerability could lead to unauthorized access to internal network resources, potentially exposing sensitive data or enabling lateral movement within the network. Confidentiality and integrity of internal systems may be compromised if attackers exploit this flaw to retrieve internal documents, configuration files, or access internal APIs. Although availability is not directly impacted, the breach of internal systems could lead to further attacks that degrade service. Organizations in sectors with sensitive data such as finance, healthcare, or government are at higher risk. The requirement for user interaction reduces the likelihood of automated widespread exploitation but targeted phishing or social engineering campaigns could facilitate attacks. The medium CVSS score reflects moderate risk, but the absence of patches means organizations must act proactively. European companies using Kerge in their web infrastructure or CMS platforms should prioritize vulnerability assessment and mitigation to avoid data breaches or network reconnaissance by threat actors.

1. Implement strict input validation and sanitization on all user-supplied data that could influence server-side requests to prevent injection of malicious URLs. 2. Restrict outbound HTTP/HTTPS requests from the Kerge server to only trusted domains or IP ranges using firewall rules or application-level allowlists. 3. Employ network segmentation to isolate internal services and sensitive resources from the web-facing servers running Kerge. 4. Monitor server logs and network traffic for unusual outbound requests or patterns indicative of SSRF exploitation attempts. 5. Educate users about phishing and social engineering risks to reduce the chance of user interaction facilitating exploitation. 6. Stay updated with LMPixels vendor communications for patches or security advisories and apply updates promptly once available. 7. Consider deploying Web Application Firewalls (WAF) with SSRF detection capabilities to block suspicious requests. 8. Conduct regular security assessments and penetration testing focusing on SSRF and related vulnerabilities in the Kerge environment.
