CVE-2025-62740 identifies a missing authorization vulnerability in the WP-CRM System WordPress plugin developed by Mario Peshev, affecting versions up to and including 3.4.5. The vulnerability arises from incorrectly configured access control security levels, which fail to properly restrict user permissions within the CRM system. This misconfiguration allows an attacker with some level of access to the WordPress environment to bypass authorization checks and perform actions or access data that should be restricted. The flaw does not require user interaction but does require the attacker to have access to the WordPress site, potentially through compromised credentials or other means. The vulnerability impacts the confidentiality and integrity of CRM data, as unauthorized users may view, modify, or delete sensitive customer information. No public exploits have been reported to date, and no official patches or CVSS scores are currently available. The vulnerability was reserved in October 2025 and published in December 2025, indicating recent discovery. The WP-CRM System plugin is widely used by small and medium enterprises (SMEs) to manage customer relationships within WordPress, making this vulnerability significant for organizations relying on this plugin for business operations.

For European organizations, the missing authorization vulnerability in WP-CRM System poses a significant risk to the confidentiality and integrity of customer data managed within WordPress environments. Unauthorized access could lead to data breaches involving personal and business-critical information, regulatory non-compliance (e.g., GDPR violations), and reputational damage. SMEs, which commonly use WordPress and related CRM plugins, may be particularly vulnerable due to limited cybersecurity resources. The ability to bypass access controls could also enable attackers to manipulate CRM data, disrupt business processes, or use the compromised system as a pivot point for further network intrusion. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits once details become widely known. The impact on availability is likely limited but cannot be ruled out if attackers modify or delete critical data.

Organizations should proactively audit their WP-CRM System plugin versions and upgrade to the latest version once a patch addressing CVE-2025-62740 is released. Until a patch is available, administrators should review and tighten access control configurations within the plugin and WordPress to minimize unnecessary privileges. Implementing the principle of least privilege for all WordPress users can reduce the risk of exploitation. Monitoring WordPress logs and CRM activity for unusual access patterns or unauthorized actions is critical for early detection. Employing web application firewalls (WAFs) with rules targeting unauthorized access attempts can provide additional protection. Regular backups of CRM data should be maintained to enable recovery in case of data manipulation or loss. Finally, educating users about credential security and enforcing strong authentication mechanisms will help prevent initial access by attackers.
