CVE-2026-2362: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in joedolson WP Accessibility
The WP Accessibility plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via the 'alt' attribute of images processed by the "Long Description UI" feature in all versions up to, and including, 2.3.1. This is due to the plugin's JavaScript retrieving the alt attribute using getAttribute() and unsafely concatenating it into innerHTML and insertAdjacentHTML calls without proper sanitization or escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires the "Long Description UI" setting to be enabled and set to "Link to description."
AI Analysis
Technical Summary
The WP Accessibility plugin for WordPress suffers from a stored DOM-based XSS vulnerability due to improper neutralization of input during web page generation (CWE-79). The plugin's JavaScript retrieves the 'alt' attribute of images using getAttribute() and inserts it into innerHTML and insertAdjacentHTML calls without proper sanitization or escaping. Authenticated attackers with Contributor-level permissions or higher can exploit this by injecting arbitrary scripts via the 'alt' attribute when the Long Description UI feature is enabled and configured to 'Link to description.' This vulnerability affects all versions up to and including 2.3.1.
Potential Impact
An attacker with Contributor-level or higher access can inject persistent malicious scripts that execute in the browsers of users who view the affected pages. This can lead to information disclosure or other client-side impacts as indicated by the CVSS vector (Confidentiality and Integrity impacts are low, no availability impact). The vulnerability requires specific plugin settings and authenticated access, limiting the attack surface but still posing a risk to site users.
Mitigation Recommendations
No official patch or fix is currently documented for this vulnerability. Administrators should verify if the Long Description UI feature is enabled and set to 'Link to description' and consider disabling it as a temporary mitigation. Monitor the vendor's advisory channels for updates or patches. Since no patch is confirmed, check the vendor advisory for current remediation guidance.
