CVE-2022-1782Network attack vector

Browser script execution via unescaped Mustache values

Published May 18, 2022 · Updated Aug 3, 2024

Cross-site scripting in Erudika Para before 1.45.11 allows remote attackers to execute script in a victim's browser via template data. The compileMustache method in para-core configured the Mustache compiler with HTML escaping disabled, so context values containing markup were copied into rendered output without entity encoding. Exploitation requires a victim to view affected rendered content; the resulting script can read or modify data available to that browser session.
