CVE-2025-62929 is a missing authorization vulnerability found in the PickPlugins Testimonial Slider WordPress plugin, affecting versions up to and including 2.0.15. This vulnerability arises from incorrectly configured access control mechanisms that fail to properly verify user permissions before allowing access to sensitive testimonial slider functionalities. The flaw enables an attacker with low privileges (PR:L) to remotely exploit the vulnerability over the network (AV:N) without requiring user interaction (UI:N). The vulnerability impacts confidentiality, integrity, and availability (C:H/I:H/A:H), meaning an attacker can potentially read, modify, or delete testimonial data or manipulate the plugin’s behavior to disrupt services. The CVSS 3.1 score of 8.8 indicates a high severity level due to the combination of network accessibility, low attack complexity, and significant impact. Although no public exploits are currently known, the vulnerability’s nature suggests it could be leveraged to escalate privileges or conduct further attacks within a compromised WordPress environment. The plugin is commonly used on WordPress sites to display customer testimonials, often integrated into business websites, e-commerce platforms, and marketing pages. The lack of patch links indicates that a fix may not yet be publicly available, increasing the urgency for administrators to implement temporary mitigations or monitor for suspicious activity. The vulnerability was published on October 27, 2025, and assigned by Patchstack, a known vulnerability aggregator for WordPress plugins. Given the widespread use of WordPress in Europe and the plugin’s role in customer-facing sites, this vulnerability poses a significant risk to European organizations relying on this plugin for their web presence.

For European organizations, exploitation of CVE-2025-62929 could lead to unauthorized access to testimonial data, which may include sensitive customer information or business-critical content. Attackers could modify or delete testimonials, damaging brand reputation and customer trust. More critically, the vulnerability’s high impact on integrity and availability could allow attackers to disrupt website functionality, potentially causing downtime or defacement. This could affect e-commerce sites, marketing platforms, and corporate websites, leading to financial losses and regulatory compliance issues, especially under GDPR where unauthorized data access is a serious concern. The network-based attack vector and lack of required user interaction increase the likelihood of exploitation, making it a viable target for automated attacks or targeted campaigns. Organizations with limited patch management capabilities or those using outdated plugin versions are particularly vulnerable. The absence of known exploits in the wild currently provides a window for proactive defense, but the high severity score suggests rapid exploitation attempts may emerge. The impact extends beyond individual sites to potentially affect supply chains and third-party integrations relying on the plugin.

1. Immediately audit all WordPress sites for the presence of the PickPlugins Testimonial Slider plugin and identify affected versions (<= 2.0.15). 2. If a patch is released, apply it promptly to remediate the vulnerability. 3. Until a patch is available, restrict access to the plugin’s administrative and API endpoints using web application firewalls (WAFs) or IP whitelisting to limit exposure. 4. Implement strict role-based access controls within WordPress to ensure only trusted users have permissions to manage the plugin. 5. Monitor web server and application logs for unusual access patterns or unauthorized attempts to interact with the testimonial slider functionality. 6. Employ intrusion detection systems (IDS) to detect exploitation attempts targeting this vulnerability. 7. Consider temporarily disabling or replacing the plugin with an alternative solution if mitigation is not feasible. 8. Educate site administrators about the risk and encourage regular plugin updates and security best practices. 9. Review and enhance overall WordPress security posture, including timely updates, backups, and incident response plans. 10. Coordinate with hosting providers to implement network-level protections and rapid response capabilities.
