What is CVE-2025-3582?
The Newsletter plugin for WordPress, prior to version 8.85, fails to properly sanitize and escape certain form settings. This oversight allows high privilege users, such as administrators, to exploit the vulnerability and conduct stored Cross-Site Scripting (XSS) attacks. This poses a significant risk, particularly in multisite setups where the unfiltered_html capability is restricted, potentially leading to unauthorized script execution and data compromise.
