CVE-2025-62929 identifies a missing authorization vulnerability in the PickPlugins Testimonial Slider plugin, specifically affecting versions up to and including 2.0.15. The vulnerability arises from incorrectly configured access control security levels, which fail to properly restrict user actions within the plugin. This misconfiguration allows attackers to bypass authorization checks, potentially enabling them to manipulate testimonial content or perform other unauthorized operations that the plugin controls. The plugin is typically used in WordPress environments to display customer testimonials on websites, making it a common target for exploitation if left unpatched. Although no exploits have been reported in the wild yet, the nature of the vulnerability suggests that exploitation could be straightforward, as it does not require authentication or complex user interaction. The lack of a CVSS score indicates that the vulnerability is newly published and pending further evaluation. The missing authorization flaw impacts the integrity and potentially the availability of website content, as attackers could alter or inject misleading testimonials, damaging organizational reputation and user trust. The vulnerability’s scope is limited to websites using the affected plugin versions, but given the widespread use of WordPress and its plugins in Europe, the potential attack surface is significant. The vulnerability was reserved and published in late October 2025, with no patch currently available, underscoring the urgency for organizations to monitor vendor updates and prepare mitigation strategies.

For European organizations, the missing authorization vulnerability in the PickPlugins Testimonial Slider poses risks primarily to website integrity and trustworthiness. Unauthorized modification or injection of testimonial content can mislead customers, damage brand reputation, and erode user confidence. In sectors such as e-commerce, professional services, and public institutions where testimonials influence customer decisions, this could translate into financial losses and reputational harm. Additionally, if attackers leverage this vulnerability as a foothold, it could lead to further compromise of web infrastructure. The impact is heightened in Europe due to strict data protection regulations like GDPR, where unauthorized data manipulation or breaches can result in regulatory penalties. Organizations relying on WordPress sites with this plugin must consider the risk of unauthorized access and content tampering, which could also affect SEO rankings and customer engagement. While the vulnerability does not directly expose sensitive personal data, the indirect consequences of trust erosion and potential follow-on attacks make it a significant threat.

To mitigate CVE-2025-62929, European organizations should take the following specific actions: 1) Immediately inventory all WordPress sites to identify installations of the PickPlugins Testimonial Slider plugin and determine the version in use. 2) Monitor the vendor’s official channels for the release of a security patch and apply it promptly once available. 3) Until a patch is released, restrict access to testimonial management interfaces by implementing strict role-based access controls and limiting administrative privileges only to trusted personnel. 4) Employ web application firewalls (WAFs) with custom rules to detect and block unauthorized attempts to access or manipulate testimonial endpoints. 5) Conduct regular security audits and penetration tests focusing on plugin access controls to identify and remediate weaknesses. 6) Enable detailed logging and monitoring of testimonial-related activities to detect suspicious behavior early. 7) Educate website administrators about the risks of unauthorized access and the importance of timely updates. 8) Consider alternative testimonial plugins with stronger security postures if immediate patching is not feasible. These measures go beyond generic advice by focusing on access control hardening, proactive monitoring, and rapid patch management tailored to this specific vulnerability.
