CVE-2023-22333Network attack vector

Stored script execution via raw form-history output

Published Jan 30, 2023 · Updated Mar 28, 2025

Stored cross-site scripting in EasyMail 2.00.130 and earlier allows remote attackers to execute scripts in visitors' browsers. The administrative form-history view applies nl2br to stored submission values and emits the result as raw Blade output instead of escaped text. No authentication is required to submit a payload, but an administrative user must display the affected history content for the script to run in that browser.
