CVE-2023-6737: Shortpixel Enable Media Replace

Medium severity, CVSS 6.1. EPSS: 0.5% chance of exploitation in the next 30 days.

The Enable Media Replace plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the SHORTPIXEL_DEBUG parameter in all versions up to, and including, 4.1.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. Exploiting this vulnerability requires the attacker to know the ID of an attachment uploaded by the user they are attacking.
