Vulnerability Overview

The WP Accessibility plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 1.6.10 due to insufficient input sanitization and output escaping with a custom CSS script. This makes it possible for authenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Technical Analysis

REMEDIATION: Update to version 1.7.0, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
