CVE-2018-25053Network attack vector

Cross-site scripting via unencoded HTML interpolation

Published Dec 28, 2022 · Updated Aug 5, 2024

Cross-site scripting in Moappi json2html before 1.2.0 allows remote attackers to inject browser-executed markup through rendered JSON data. json2html.js interpolates values assigned to a template's html property directly into its output, while the patch adds a text property that applies HTML entity encoding before concatenation. Exploitation requires an application to place attacker-controlled JSON in an html template and a user to render the resulting page, enabling script execution in that page's browser context.
