Vulnerability Overview

The Quick Event Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in versions up to, and including, 9.6.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrative-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

Technical Analysis

REMEDIATION: Update to version 9.6.5, or a newer patched version --- IDENTIFIER: CWE-692 (Incomplete Denylist to Cross-Site Scripting) The product uses a denylist-based protection mechanism to defend against XSS attacks, but the denylist is incomplete, allowing XSS variants to succeed.
