Stored script execution via email marketing templates

Published Dec 18, 2025 · Updated Dec 18, 2025

Stored cross-site scripting in Kentico Xperience 13.0.92 and earlier allows remote authenticated users to run scripts in browsers. The email marketing template editor stores attacker-supplied markup that later executes when a user views the rendered template; Kentico has not published the exact missing validation or output-encoding operation. Administration access and a user viewing the crafted template are required, exposing browser-accessible data and actions without reported service interruption.
