CVE-2025-66112 identifies a missing authorization vulnerability in the WebToffee Accessibility Toolkit by WebYes, specifically affecting versions up to and including 2.0.4. This vulnerability stems from incorrectly configured access control mechanisms within the toolkit, which is designed to provide accessibility enhancements on websites. Missing authorization means that certain functions or data that should be restricted to authorized users can be accessed by unauthorized actors. This can lead to unauthorized disclosure or modification of data, potentially undermining the integrity and confidentiality of the affected systems. The vulnerability does not require user interaction to be exploited, and no authentication barriers are properly enforced, increasing the risk of exploitation. Although no known exploits have been observed in the wild yet, the flaw presents a significant risk, especially for organizations relying on this toolkit to meet accessibility standards and legal requirements. The lack of a CVSS score suggests the vulnerability is newly disclosed, and detailed impact metrics are not yet available. The vulnerability affects web environments where the toolkit is deployed, which could include a wide range of websites, from corporate portals to governmental services. The toolkit’s role in accessibility means that exploitation could also disrupt services for users relying on these features, potentially causing availability issues or reputational damage. The vulnerability was published on November 21, 2025, by Patchstack, with no patches currently linked, indicating that remediation may require vendor action or configuration changes by administrators.

For European organizations, the impact of CVE-2025-66112 could be significant due to the widespread adoption of accessibility tools to comply with stringent EU accessibility directives and regulations such as the European Accessibility Act. Unauthorized access resulting from this vulnerability could lead to exposure or manipulation of sensitive user interface components or data, potentially violating user privacy and data protection laws like GDPR. Additionally, disruption or degradation of accessibility features could result in non-compliance penalties and damage to organizational reputation, especially for public sector entities and companies serving disabled users. The vulnerability could also be leveraged as a foothold for further attacks within the network if exploited by threat actors. Organizations with high web traffic and critical online services are at greater risk, as exploitation could affect availability and user trust. Since the toolkit is embedded in websites, the scope of affected systems is broad, potentially impacting multiple departments or services within an organization. The absence of known exploits provides a window for proactive mitigation, but the risk remains elevated until patches or workarounds are implemented.

1. Monitor WebToffee and WebYes official channels for security advisories and promptly apply any released patches or updates addressing CVE-2025-66112. 2. Conduct a thorough audit of access control configurations related to the Accessibility Toolkit to ensure proper authorization checks are enforced. 3. Implement web application firewalls (WAFs) with custom rules to detect and block unauthorized access attempts targeting the toolkit’s endpoints. 4. Restrict access to administrative or sensitive functions of the toolkit to trusted IP addresses or authenticated users only. 5. Employ continuous monitoring and logging of web application access to identify anomalous behavior indicative of exploitation attempts. 6. Educate web development and security teams about the vulnerability to ensure secure coding and configuration practices in future deployments. 7. Consider isolating or sandboxing the accessibility toolkit components to limit the blast radius in case of compromise. 8. Review compliance with accessibility and data protection regulations to prepare for potential audits or incident response scenarios related to this vulnerability.
