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 flaw arises from incorrectly configured access control security levels, which fail to properly restrict unauthorized users from performing certain actions within the CRM system. This vulnerability allows remote attackers to modify data without authentication, compromising the integrity of the CRM data. The CVSS 3.1 base score is 5.3 (medium), reflecting that the attack vector is network-based (AV:N), requires no privileges (PR:N), and no user interaction (UI:N), but only impacts integrity (I:L) without affecting confidentiality or availability. The vulnerability does not require the attacker to be authenticated, making exploitation easier. Although no known exploits have been reported in the wild, the lack of authorization checks poses a significant risk to organizations relying on this plugin for managing customer data. The vulnerability's impact is limited to data integrity, meaning attackers could alter CRM records, potentially leading to misinformation, fraud, or operational disruptions. No patches or mitigation links are currently provided, indicating that organizations should monitor vendor communications closely. The vulnerability is particularly relevant to WordPress sites using WP-CRM System, which is popular among small and medium enterprises for customer relationship management. Given WordPress's widespread use in Europe, this vulnerability could affect a broad range of organizations if left unaddressed.

For European organizations, the missing authorization vulnerability in WP-CRM System could lead to unauthorized modification of customer data, undermining data integrity and trustworthiness. This may result in operational disruptions, erroneous business decisions, or compliance issues, especially under GDPR where data accuracy is critical. Although confidentiality and availability are not directly impacted, integrity breaches can have cascading effects such as financial fraud or reputational damage. Organizations relying on WP-CRM System for customer management, sales tracking, or marketing automation may face risks of data tampering by remote attackers without authentication. The medium severity score reflects moderate risk; however, the ease of exploitation and lack of user interaction increase the urgency to address the issue. The absence of known exploits in the wild currently limits immediate threat, but the vulnerability could be targeted in the future. European SMEs and enterprises using WordPress plugins for CRM functions should prioritize assessment and remediation to prevent potential exploitation.

1. Monitor official vendor channels and security advisories for patches or updates addressing CVE-2025-62740 and apply them promptly once available. 2. In the interim, review and tighten access control configurations within the WP-CRM System plugin settings to restrict unauthorized actions as much as possible. 3. Implement Web Application Firewall (WAF) rules to detect and block suspicious requests targeting WP-CRM endpoints. 4. Conduct regular audits of CRM data integrity and logs to identify unauthorized modifications early. 5. Limit exposure by restricting access to the WordPress admin and plugin interfaces via IP whitelisting or VPN where feasible. 6. Educate administrators on the risks of missing authorization vulnerabilities and encourage prompt patch management. 7. Consider isolating the CRM plugin environment or using alternative CRM solutions with stronger security controls if immediate patching is not possible. 8. Employ intrusion detection systems to monitor for anomalous activities related to WP-CRM System usage. These measures go beyond generic advice by focusing on configuration hardening, monitoring, and access restrictions tailored to this specific plugin vulnerability.
