CVE-2025-58976 is a security vulnerability classified under CWE-862 (Missing Authorization) found in the Accessibility Checker product by Equalize Digital, affecting versions up to 1.31.0. This vulnerability arises due to improperly configured access control mechanisms, allowing users with limited privileges (PR:L - Privileges Required: Low) to access or perform actions beyond their authorized scope without proper authorization checks. The vulnerability does not require user interaction (UI:N) and can be exploited remotely (AV:N - Attack Vector: Network) with low attack complexity (AC:L). The impact is limited to confidentiality (C:L) with no direct effect on integrity or availability. Specifically, an attacker with low-level privileges could potentially access sensitive information or data that should be restricted, due to missing or incorrect authorization enforcement within the application. The vulnerability does not appear to have known exploits in the wild at this time, and no patches have been linked yet. The CVSS v3.1 base score is 4.3, indicating a medium severity level. The issue is significant because accessibility checkers are often integrated into web development and compliance workflows, potentially exposing sensitive audit data or user information if authorization is not properly enforced.

For European organizations, the impact of CVE-2025-58976 could be notable, especially for those relying on Equalize Digital's Accessibility Checker to ensure compliance with accessibility standards such as the EU Web Accessibility Directive and EN 301 549. Unauthorized access to accessibility audit data could lead to exposure of sensitive information about website structures, user data, or internal compliance statuses. This could be leveraged by attackers for reconnaissance or to identify weaknesses in web applications. Furthermore, given the increasing regulatory focus on digital accessibility in Europe, any compromise or misuse of accessibility tools could result in reputational damage and potential regulatory scrutiny. While the vulnerability does not directly affect system integrity or availability, the confidentiality breach could undermine trust in accessibility compliance processes and expose organizations to indirect risks such as targeted phishing or social engineering attacks.

To mitigate this vulnerability, European organizations using Accessibility Checker by Equalize Digital should: 1) Immediately review and restrict user privileges within the application to the minimum necessary, ensuring that low-privilege users do not have access to sensitive audit data or administrative functions. 2) Implement additional access control layers at the network or application gateway level to restrict access to the Accessibility Checker interface to trusted users and IP ranges. 3) Monitor application logs for unusual access patterns or attempts to access unauthorized resources. 4) Engage with Equalize Digital to obtain official patches or updates addressing CVE-2025-58976 as soon as they become available and apply them promptly. 5) Conduct internal audits of accessibility tool configurations and user roles to verify that authorization controls are correctly implemented. 6) Consider isolating the Accessibility Checker environment from critical production systems to limit potential exposure. These steps go beyond generic advice by focusing on privilege management, network-level controls, and proactive monitoring tailored to this specific vulnerability.
