Vulnerability Overview

The WP Chat App plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'imageAlt' block attribute in all versions up to, and including, 3.6.2 due to insufficient input sanitization and output escaping on user supplied attributes. 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.

Technical Analysis

REMEDIATION: Update to version 3.6.3, or a newer patched version --- IDENTIFIER: CWE-20 (Improper Input Validation) The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
