CVE-2025-49920 identifies a Missing Authorization vulnerability in the accessiBe Web Accessibility product, specifically affecting versions up to 2.10. The vulnerability stems from incorrectly configured access control security levels, which fail to properly restrict user permissions. This misconfiguration allows an attacker with low privileges (PR:L) to access or perform actions beyond their authorization scope without requiring any user interaction (UI:N). The attack vector is network-based (AV:N), meaning exploitation can occur remotely without physical access. The vulnerability impacts confidentiality and integrity to a limited extent, as unauthorized access could expose sensitive information or permit unauthorized modifications, but does not affect availability. The CVSS score of 5.4 (medium severity) reflects these factors. No public exploits have been reported, but the vulnerability’s presence in a widely used web accessibility tool raises concerns, especially for organizations subject to strict accessibility and data protection regulations. The lack of available patches at the time of publication necessitates immediate mitigation through configuration audits and access control hardening. Given the nature of the product, which is integrated into websites to enhance accessibility compliance, exploitation could lead to unauthorized data exposure or manipulation within web environments.

For European organizations, the impact of this vulnerability could be significant, especially for those relying on accessiBe’s Web Accessibility tool to meet legal accessibility standards such as the EU Web Accessibility Directive. Unauthorized access due to missing authorization controls could lead to exposure of user data or unauthorized changes to accessibility settings, potentially resulting in compliance violations and reputational damage. While the vulnerability does not directly compromise system availability, the confidentiality and integrity risks could affect sensitive user information or website content. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, may face increased risks. Additionally, failure to maintain proper access controls could undermine trust in digital accessibility solutions, impacting user experience and regulatory compliance.

1. Immediately audit and review all access control configurations within the accessiBe Web Accessibility implementation to ensure proper authorization checks are enforced. 2. Limit user privileges strictly to the minimum necessary roles to reduce the attack surface. 3. Monitor network traffic and access logs for unusual or unauthorized access attempts related to the accessiBe product. 4. Engage with accessiBe vendor support to obtain patches or updates addressing this vulnerability as soon as they become available. 5. Implement web application firewalls (WAF) with rules tailored to detect and block unauthorized access attempts targeting the affected product. 6. Conduct regular security assessments and penetration testing focusing on access control mechanisms within web accessibility tools. 7. Educate development and operations teams about secure configuration practices for third-party accessibility tools. 8. Consider isolating the accessibility tool’s administrative interfaces behind additional authentication layers or VPNs where feasible.
