CVE-2025-62106 identifies a missing authorization vulnerability in the WP-CRM System WordPress plugin developed by Mario Peshev, affecting all versions up to and including 3.4.5. The vulnerability arises from incorrectly configured access control security levels within the plugin, allowing attackers with low privileges (PR:L) to bypass authorization checks and perform unauthorized actions remotely (AV:N) without requiring user interaction (UI:N). The vulnerability impacts confidentiality, integrity, and availability (C:H/I:H/A:H) of the CRM system and potentially the underlying WordPress environment. This means an attacker could access sensitive customer data, modify records, or disrupt CRM services. The CVSS score of 8.8 reflects the high severity and ease of exploitation. Although no known exploits have been reported in the wild, the vulnerability's nature makes it a prime target for attackers seeking to compromise business-critical CRM data. The vulnerability was reserved in October 2025 and published in January 2026, indicating recent discovery and disclosure. The WP-CRM System plugin is widely used by small and medium enterprises (SMEs) to manage customer relationships, making this vulnerability particularly impactful for organizations relying on this tool for business operations.

For European organizations, the impact of CVE-2025-62106 can be significant. Compromise of the WP-CRM System can lead to unauthorized disclosure of sensitive customer data, violating GDPR and other privacy regulations, resulting in legal and financial penalties. Integrity breaches could allow attackers to alter customer records, leading to operational disruptions and loss of trust. Availability impacts could disrupt CRM services, affecting sales, customer support, and business continuity. SMEs, which form a large part of the European economy and often rely on WordPress plugins like WP-CRM System, are particularly vulnerable. The breach of CRM data can also serve as a foothold for further attacks within the corporate network. Given the remote exploitability and lack of required user interaction, attackers can automate exploitation attempts, increasing the risk of widespread compromise across European organizations using this plugin.

Organizations should immediately inventory their WordPress installations to identify the presence and version of the WP-CRM System plugin. Until an official patch is released, restrict access to the plugin’s administrative interfaces using network-level controls such as IP whitelisting or VPN access. Implement strict WordPress user role management to minimize privileges assigned to users interacting with the plugin. Monitor logs for unusual access patterns or privilege escalations related to the plugin. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting WP-CRM System endpoints. Once a patch is available, prioritize its deployment across all affected systems. Additionally, conduct regular backups of CRM data and test restoration procedures to mitigate potential data loss. Educate administrators about the risks of missing authorization vulnerabilities and the importance of timely patching and access control.
