CVE-2026-24587 identifies a missing authorization vulnerability in the kutsy AJAX Hits Counter + Popular Posts Widget, specifically within the ajax-hits-counter functionality. This vulnerability arises from incorrectly configured access control security levels, allowing unauthorized users to interact with the widget's AJAX endpoints without proper permission checks. The affected versions include all releases up to and including 0.10.210305. The lack of authorization means that attackers could potentially manipulate hit counters, retrieve sensitive usage data, or interfere with the widget's intended operation. While no exploits have been observed in the wild, the vulnerability presents a significant risk because it undermines the integrity and confidentiality of the data managed by the widget. The vulnerability does not require authentication or user interaction, increasing its exploitability. The widget is commonly used in WordPress environments to display popular posts and track hits, making it a target for attackers seeking to manipulate website analytics or gain unauthorized insights. The absence of a CVSS score necessitates an expert severity assessment, which rates this vulnerability as high due to the direct impact on access control and potential for unauthorized data access or manipulation.

For European organizations, this vulnerability could lead to unauthorized manipulation of website analytics data, impacting the integrity and reliability of visitor metrics. Attackers might exploit the flaw to inflate or deflate hit counts, skewing business intelligence and decision-making processes. Additionally, unauthorized access to usage data could expose sensitive information about user behavior or website performance. This could undermine trust in digital services, especially for media, e-commerce, and content-driven organizations relying on accurate analytics. The vulnerability may also be leveraged as a foothold for further attacks if combined with other weaknesses. Given the widespread use of WordPress and related plugins across Europe, the scope of affected systems could be substantial. The lack of authentication requirements increases the risk of automated exploitation attempts, potentially leading to denial of service or data integrity issues. Organizations in sectors with strict data protection regulations, such as finance, healthcare, and public services, face heightened compliance risks if this vulnerability is exploited.

European organizations should immediately audit their use of the kutsy AJAX Hits Counter + Popular Posts Widget and identify affected versions. Until an official patch is released, implement strict access control measures at the web server or application firewall level to restrict access to the ajax-hits-counter endpoints only to authorized users or internal networks. Employ web application firewalls (WAFs) with custom rules to detect and block unauthorized AJAX requests targeting the widget. Conduct thorough code reviews to ensure proper authorization checks are enforced within the widget's AJAX handlers. Monitor web server logs for unusual or unauthorized access patterns related to the widget. Consider temporarily disabling the widget if it is not critical to website functionality. Stay informed about vendor updates and apply patches promptly once available. Additionally, implement robust security monitoring and incident response plans to detect and respond to potential exploitation attempts. Educate development and security teams about the risks of missing authorization controls to prevent similar issues in other components.
