CVE-2024-37549Network attack vector

Browser script execution through stored plugin settings

Published Jul 21, 2024 · Updated Apr 28, 2026

Stored XSS in PDFCrowd Save as PDF Plugin 4.0.0 and earlier allows remote authenticated users to execute script in another user's browser. The upstream changelog states that the flaw resides in the plugin settings, but public sources do not identify the affected setting, handler, or faulty input-neutralization operation. Exploitation requires high-privileged access and another user's interaction; the script runs with the data access and actions available to that browser session.
