CVE-2024-37271Network attack vector

Stored XSS via unescaped Quick Print content

Published Jul 22, 2024 · Updated Apr 28, 2026

Stored XSS in PMB 3.27.0 and earlier lets remote authenticated users execute scripts through crafted WordPress post content. Quick Print places post content into generated pages without output escaping, causing stored markup to execute when an affected print page loads. Exploitation requires high privileges to supply malicious content and user interaction to open the affected page; consequences remain confined to the viewing browser session.
