CVE-2025-10706 is a vulnerability classified under CWE-862 (Missing Authorization) found in the ClassifiedPro - reCommerce WordPress theme developed by Cridio Studio. The vulnerability exists in the 'cwp_addons_update_plugin_cb' function, which lacks proper capability checks before allowing plugin installation. This flaw affects all versions up to and including 1.0.14. An authenticated attacker with subscriber-level access or higher can exploit this vulnerability to install arbitrary plugins on the WordPress site. Since plugins can contain malicious code, this can lead to remote code execution (RCE) on the server hosting the WordPress instance. The attack does not require user interaction beyond authentication and leverages a nonce provided by the CubeWP Framework plugin, which is a prerequisite for the exploit. The CVSS v3.1 score is 8.8, indicating a high severity with network attack vector, low attack complexity, requiring privileges but no user interaction, and impacting confidentiality, integrity, and availability. No patches are currently available, and no exploits have been reported in the wild yet. The vulnerability is particularly dangerous because subscriber-level users are often considered low-privilege, and this flaw escalates their capabilities significantly.

For European organizations, especially those operating WordPress sites with the ClassifiedPro theme, this vulnerability poses a significant risk. Attackers gaining subscriber-level access—potentially through phishing, credential stuffing, or other means—can install malicious plugins, leading to full server compromise via remote code execution. This can result in data breaches, defacement, service disruption, or use of the compromised server as a pivot point for further attacks. Organizations handling sensitive personal data under GDPR may face regulatory penalties if such breaches occur. The impact extends to e-commerce platforms, classified ad sites, and other business-critical applications using this theme. The vulnerability undermines trust in the affected websites and can cause reputational damage. Given the widespread use of WordPress in Europe and the popularity of themes like ClassifiedPro, the threat surface is considerable. The lack of known exploits currently provides a window for proactive mitigation.

1. Immediately audit user roles and permissions on WordPress sites using the ClassifiedPro theme, ensuring that subscriber-level users are strictly controlled and monitored. 2. Restrict plugin installation capabilities to trusted administrators only, and consider disabling plugin installation for lower-privilege users via custom role management plugins or WordPress configuration. 3. Monitor plugin installation logs and file system changes for unauthorized activity. 4. Implement Web Application Firewalls (WAF) with rules to detect and block suspicious plugin installation requests targeting the vulnerable function. 5. Isolate WordPress environments to limit the impact of potential RCE, such as running sites in containers or with strict OS-level permissions. 6. Engage with the theme vendor (Cridio Studio) for patches or updates and apply them promptly once released. 7. Educate users about credential security to prevent unauthorized access at subscriber level. 8. Consider temporarily disabling or removing the CubeWP Framework plugin if feasible, as it provides the nonce required for exploitation. 9. Conduct penetration testing focusing on privilege escalation vectors related to plugin management. 10. Maintain regular backups and incident response plans to recover quickly if exploitation occurs.
