CVE-2025-62153 identifies a Missing Authorization vulnerability in the Graham Quick Interest Slider plugin, affecting versions up to and including 3.1.5. The vulnerability arises from incorrectly configured access control security levels, which fail to properly restrict unauthorized users from performing actions intended only for authorized personnel. This type of flaw typically allows attackers to bypass authentication or authorization checks, potentially enabling them to manipulate slider content, alter configurations, or access sensitive data managed by the plugin. The Quick Interest Slider is a web component used to create interactive interest sliders on websites, often integrated into content management systems or custom web applications. The absence of a CVSS score indicates that the vulnerability has not yet been fully assessed, but the nature of missing authorization suggests a significant risk. No public exploits have been reported, but the vulnerability's presence in widely deployed web components could make it an attractive target once exploit code becomes available. The vulnerability was reserved in October 2025 and published in December 2025, indicating recent discovery and disclosure. The lack of patch links suggests that fixes may not yet be available, emphasizing the need for immediate mitigation through configuration review and access restrictions. The vulnerability does not require user interaction or authentication to exploit, increasing its risk profile. Organizations using this plugin should consider the potential for unauthorized access or modification of web content, which could lead to reputational damage, data integrity issues, or further exploitation of the web environment.

For European organizations, the impact of CVE-2025-62153 could be significant, particularly for those relying on the Graham Quick Interest Slider plugin within their web infrastructure. Unauthorized access to the plugin's functionality could allow attackers to manipulate website content, potentially defacing sites, injecting malicious content, or exposing sensitive information. This could lead to reputational damage, loss of customer trust, and regulatory compliance issues, especially under GDPR requirements concerning data protection and integrity. The vulnerability could also serve as a foothold for further attacks within the network if leveraged to escalate privileges or move laterally. Sectors such as e-commerce, media, and public services, which often use interactive web components, may be particularly vulnerable. The absence of authentication requirements for exploitation increases the risk of automated or remote attacks, potentially affecting a broad range of organizations. Additionally, the lack of known exploits currently provides a window for proactive defense, but also means organizations must act swiftly to prevent future exploitation. Failure to address this vulnerability could result in service disruptions or data breaches, with associated financial and legal consequences.

To mitigate CVE-2025-62153, European organizations should immediately audit their use of the Graham Quick Interest Slider plugin, verifying the access control configurations to ensure that only authorized users can manage or interact with the slider settings. Until an official patch is released, restrict plugin management interfaces to trusted administrators and implement network-level controls such as IP whitelisting or VPN access for administrative functions. Monitor web server and application logs for unusual or unauthorized access attempts related to the plugin endpoints. Employ web application firewalls (WAFs) to detect and block suspicious requests targeting the slider plugin. Regularly update the plugin as soon as the vendor releases a security patch addressing this vulnerability. Additionally, conduct penetration testing focused on authorization controls within the web application to identify similar weaknesses. Educate web administrators about the risks of misconfigured access controls and enforce strict role-based access policies. Finally, maintain an incident response plan to quickly address any exploitation attempts or breaches involving this vulnerability.
