Vulnerability Overview

WordPress Core is vulnerable to Stored Cross-Site Scripting via the footnotes block in versions between 6.3 and 6.3.1 due to insufficient input sanitization and output escaping on the footnotes block. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Technical Analysis

REMEDIATION: Update to version 6.3.2, 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.
