CVE-2025-49920 identifies a missing authorization vulnerability in the accessiBe Web Accessibility product, versions up to 2.10. The flaw arises from incorrectly configured access control security levels, which allow users with limited privileges (PR:L) to perform actions or access resources beyond their authorization scope. The vulnerability is exploitable remotely over the network (AV:N) without requiring user interaction (UI:N), and the attack complexity is low (AC:L). The impact affects confidentiality and integrity, as unauthorized access could expose sensitive data or allow unauthorized modifications, but does not affect availability. The vulnerability does not require privilege escalation beyond limited privileges, indicating that an attacker must have some level of authenticated access but can then bypass further authorization checks. No known public exploits have been reported yet, but the presence of this vulnerability in a widely used web accessibility tool raises concerns, especially for organizations relying on accessiBe to meet accessibility compliance. The lack of patch links suggests that a fix may not yet be publicly available, emphasizing the need for interim mitigations. The vulnerability was reserved in June 2025 and published in October 2025, indicating recent discovery and disclosure. Given the nature of the product—integrated into websites to provide accessibility features—this vulnerability could expose sensitive user data or administrative functions if exploited.

For European organizations, the impact of CVE-2025-49920 can be significant, particularly for those mandated to comply with accessibility regulations such as the EU Web Accessibility Directive and EN 301 549 standards. Unauthorized access due to missing authorization controls could lead to exposure of personal data, violating GDPR requirements and potentially resulting in regulatory penalties. Integrity impacts could allow attackers to alter accessibility settings or content, undermining trust and compliance. Since accessiBe is a third-party tool integrated into websites, exploitation could affect customer-facing portals, leading to reputational damage and loss of user confidence. The medium severity rating reflects moderate risk, but the ease of exploitation by authenticated users raises concerns for insider threats or compromised accounts. Organizations in sectors with high regulatory scrutiny, such as finance, healthcare, and government, may face amplified risks. Additionally, the lack of known exploits currently provides a window for proactive mitigation before active attacks emerge.

European organizations should immediately audit their deployment of accessiBe Web Accessibility versions up to 2.10 to identify affected instances. Until a vendor patch is released, organizations should implement strict access control reviews to ensure that users have only necessary privileges and that privilege escalation paths are closed. Monitoring and logging of accessiBe administrative and user actions should be enhanced to detect anomalous behavior indicative of exploitation attempts. Network segmentation and application-layer firewalls can help restrict access to the management interfaces of accessiBe components. Organizations should engage with accessiBe support channels to obtain information on patches or workarounds and apply updates promptly once available. Additionally, consider alternative accessibility solutions if remediation timelines are uncertain. Regular security assessments and penetration testing focusing on access control mechanisms in integrated third-party tools are recommended to prevent similar issues.
