CVE-2025-62052 identifies a missing authorization vulnerability in the One Page Express Companion plugin developed by Horea Radu, affecting versions up to and including 1.6.43. Missing authorization means that certain functions or endpoints within the plugin do not properly verify whether the user has the necessary permissions to perform actions or access data. This can allow unauthenticated or unauthorized users to execute privileged operations, potentially including modifying website content, accessing sensitive configuration data, or manipulating plugin-specific features. The vulnerability is present in a WordPress plugin widely used for building one-page websites, which increases its attack surface due to the popularity of WordPress in Europe and globally. Although no public exploits have been reported yet, the lack of authorization checks is a critical security flaw that can be leveraged by attackers to compromise website integrity and confidentiality. The absence of a CVSS score suggests that the vulnerability is newly disclosed and not yet fully assessed, but the nature of missing authorization typically implies a high risk. The vulnerability was reserved on October 7, 2025, and published on October 22, 2025, indicating recent discovery. No patches or fixes are currently linked, so affected users must monitor vendor updates closely. The vulnerability does not require user interaction or authentication, increasing the ease of exploitation. Given the plugin’s role in website content management, exploitation could lead to defacement, data leakage, or further pivoting into the hosting environment.

For European organizations, this vulnerability poses a significant risk to the confidentiality, integrity, and availability of websites using the One Page Express Companion plugin. Exploitation could allow attackers to bypass access controls, leading to unauthorized content changes, exposure of sensitive information, or insertion of malicious code. This can damage organizational reputation, lead to data breaches, and disrupt business operations, especially for companies relying on their web presence for customer engagement or e-commerce. The impact is heightened for sectors with strict data protection requirements, such as finance, healthcare, and government, where unauthorized access could violate GDPR and other regulations. Additionally, compromised websites could be used as attack vectors for further intrusions or to distribute malware. The lack of known exploits currently reduces immediate risk but also means organizations should act proactively. The widespread use of WordPress in Europe means many small to medium enterprises could be vulnerable, increasing the potential scale of impact.

Organizations should immediately inventory their WordPress installations to identify the presence of the One Page Express Companion plugin and its version. Until an official patch is released, administrators should restrict access to the plugin’s administrative interfaces using web application firewalls (WAFs) or IP whitelisting to limit exposure. Implementing strict role-based access controls within WordPress can reduce the risk of unauthorized actions. Monitoring web server and application logs for unusual activity related to the plugin endpoints is critical for early detection. Organizations should subscribe to vendor and security mailing lists for timely patch releases and apply updates promptly once available. If feasible, temporarily disabling or uninstalling the plugin can mitigate risk. Additionally, conducting security audits and penetration testing focused on plugin vulnerabilities can help identify exploitation attempts. Backup procedures should be verified to ensure rapid recovery in case of compromise. Finally, educating web administrators about the risks of missing authorization vulnerabilities can improve overall security posture.
