CVE-2026-2413 Scanner

Ally - Web Accessibility & Usability is a WordPress plugin designed to enhance website accessibility and usability, primarily for individuals with disabilities. It is widely employed by web developers and accessibility consultants to ensure websites meet legal requirements and standards for usability. The plugin integrates seamlessly with WordPress websites, providing tools such as screen reader compatibility, keyboard navigation improvements, and other accessibility features. Ally helps organizations to improve website compliance with accessibility standards, making their content more user-friendly and accessible to a broader audience. The plugin supports customization, allowing users to tailor accessibility options according to individual needs and preferences. By offering these functionalities, Ally aids companies in broadening their user base, including individuals who might otherwise encounter challenges when navigating standard web content.

The vulnerability in question is a SQL Injection, which is a type of security flaw affecting the Ally - Web Accessibility & Usability plugin for WordPress up to version 4.0.3. This vulnerability arises due to insufficient escaping in the user-supplied URL parameter, particularly in the `get_global_remediations()` method. Here, data is directly concatenated into SQL queries, making it vulnerable to malicious SQL code injections. This type of vulnerability allows attackers to manipulate SQL commands, potentially leading to unauthorized database queries. The primary risk entails attackers extracting sensitive information from the database, exploiting the vulnerability through blind SQL injection techniques. This issue highlights the necessity of rigorous input sanitization to prevent injection and potential data breaches, which could compromise sensitive user information.

The technical details of the vulnerability shed light on how attackers exploit it. Unauthenticated users can introduce additional SQL queries to existing ones by manipulating the URL path parameter. This vulnerability is possible because the `esc_url_raw()` function does not adequately sanitize SQL metacharacters, leaving the plugin open to injections involving quotes and parentheses characters. Attackers leverage such inputs to execute time-based blind SQL injections, particularly when the "Remediation" module is active within the plugin. Attackers can execute arbitrary SQL commands via injected sleep statements, which are confirmed through the detection of delays in server response times. As a result, information such as usernames, passwords, or other sensitive data may be disclosed.

When exploited, this SQL Injection vulnerability can lead to severe consequences, primarily involving the disclosure of sensitive data stored within the WordPress database. Malicious actors can gain access to user information, including usernames, password hashes, and potentially even personal data. Such information exposure poses risks of identity theft, unauthorized access, and further exploitation of the database system. Additionally, the compromised data could result in reputational damage for the affected website, leading to potential legal implications and loss of user trust. Therefore, addressing vulnerabilities like these is critical to safeguarding sensitive information and maintaining the integrity of web applications.
