CVE-2025-14793 identifies a Server-Side Request Forgery (SSRF) vulnerability in the DK PDF – WordPress PDF Generator plugin, maintained by torstenbulk, affecting all versions up to and including 2.3.0. The vulnerability resides in the 'addContentToMpdf' function, which improperly handles user input, allowing authenticated users with author-level permissions or higher to induce the server to send crafted HTTP requests to arbitrary destinations. SSRF vulnerabilities enable attackers to bypass network restrictions, potentially accessing internal services that are not exposed externally, such as internal APIs, databases, or cloud metadata services. In this case, the attacker can leverage the SSRF to query or modify information on internal systems, which could lead to data exposure or further compromise. The vulnerability requires authentication at the author level, which is a moderately privileged role in WordPress, but does not require user interaction beyond authentication. The CVSS 3.1 base score is 5.0 (medium severity), reflecting the network attack vector, low attack complexity, and limited privileges required. No public exploits have been reported yet, but the vulnerability's presence in a popular WordPress plugin makes it a potential target for attackers. The absence of available patches at the time of reporting increases the urgency for mitigation. The vulnerability's scope is confined to confidentiality impact, with no direct integrity or availability impact reported. The plugin's widespread use in WordPress sites globally, including Europe, raises concerns for organizations relying on this plugin for PDF generation capabilities.

For European organizations, this SSRF vulnerability poses a significant risk of internal network reconnaissance and unauthorized data access. Attackers with author-level access could exploit the vulnerability to access internal services that are typically protected behind firewalls, such as internal APIs, databases, or cloud metadata endpoints, potentially leading to data leakage or further lateral movement within the network. Confidentiality of sensitive information could be compromised, especially in environments where internal services contain personal data or business-critical information. Given the GDPR regulatory environment in Europe, any data breach resulting from exploitation could lead to substantial compliance penalties and reputational damage. Additionally, organizations using WordPress extensively for public-facing websites, intranets, or customer portals are at higher risk. The vulnerability does not directly impact system integrity or availability but can be a stepping stone for more severe attacks if combined with other vulnerabilities or misconfigurations. The medium severity rating indicates that while the threat is not immediately critical, it requires timely attention to prevent escalation.

To mitigate CVE-2025-14793, European organizations should first restrict author-level privileges to trusted users only, minimizing the attack surface. Implement strict access controls and regularly audit user roles within WordPress environments. Network segmentation should be enforced to isolate internal services from the web server hosting WordPress, limiting the SSRF attacker's ability to reach sensitive internal endpoints. Employ outbound web request monitoring and filtering on the web server to detect and block suspicious SSRF attempts. Until an official patch is released, consider disabling or replacing the DK PDF plugin with alternative PDF generation tools that do not exhibit this vulnerability. Web application firewalls (WAFs) can be configured to detect and block SSRF patterns targeting internal IP ranges or unusual request destinations. Regularly update WordPress and all plugins to the latest versions once patches become available. Conduct internal penetration testing focusing on SSRF vectors to identify and remediate similar weaknesses. Finally, maintain comprehensive logging and alerting to quickly detect exploitation attempts.
