CVE-2025-49028Network attack vector

Stored XSS via forged privileged-user request

Published Dec 31, 2025 · Updated Dec 31, 2025

Stored XSS in the Zoho ZeptoMail WordPress plugin 3.3.1 and earlier allows remote attackers to inject script through a forged request. Public records identify CSRF leading to stored XSS but do not disclose the affected handler, parameter, or missing validation operation. Exploitation requires an authenticated privileged user to visit an attacker-controlled page or submit a crafted form, after which the stored script can execute in later browser sessions.
