CVE-2025-62929 is a missing authorization vulnerability identified in the PickPlugins Testimonial Slider plugin, a WordPress plugin used to display testimonials on websites. The vulnerability affects all versions up to and including 2.0.15. It arises due to incorrectly configured access control security levels, allowing attackers with low privileges (PR:L) to bypass authorization checks and perform unauthorized actions remotely 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 could potentially access sensitive data, modify content, or disrupt service. The CVSS score of 8.8 reflects its high severity. Although no public exploits are currently known, the low attack complexity and absence of required user interaction make exploitation feasible. The vulnerability likely enables privilege escalation or unauthorized administrative actions within the plugin's functionality, which could lead to website defacement, data leakage, or further compromise of the hosting environment. The plugin is commonly used in WordPress environments, which are prevalent across many European organizations, particularly in marketing, e-commerce, and content management sectors.

For European organizations, the impact of CVE-2025-62929 can be significant. Compromise of the Testimonial Slider plugin could lead to unauthorized data disclosure, including customer testimonials or other sensitive content, damaging organizational reputation and violating data protection regulations such as GDPR. Integrity violations could allow attackers to alter website content, potentially injecting malicious code or misleading information, which could harm customer trust and brand image. Availability impacts could disrupt website functionality, leading to loss of business or service interruptions. Given the widespread use of WordPress and associated plugins in Europe, especially in countries with large digital economies, the vulnerability poses a risk to a broad range of sectors including retail, finance, and media. Additionally, exploitation could serve as a foothold for further lateral movement within corporate networks, increasing the risk of more severe breaches.

Organizations should immediately inventory their WordPress installations to identify the presence of the PickPlugins Testimonial Slider plugin and verify the version in use. 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 role-based access controls within WordPress to limit user privileges, ensuring that only trusted administrators have modification rights. Monitor web server and application logs for unusual activity related to the plugin endpoints. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the plugin. Once the vendor releases a patch, apply it promptly and validate the fix in a test environment before production deployment. Additionally, conduct regular security assessments and penetration testing focused on plugin vulnerabilities. Educate website administrators about the risks of installing unverified plugins and the importance of timely updates.
