Summary

The package `jQuery` before 1.12.0, between 1.12.2 and 2.1.4 and between 2.2.2 and 2.2.4 is vulnerable to `XSS`. The function `jQuery.parseHTML()` in the file `src/core/parseHTML.js` doesn't stop scripts or inline event handlers from being executed immediately, which could result in XSS as the attacker could embed malicious scripts in the HTML (img nodes with embedded src url's which are pre-loaded when the page is requested) which would get executed immediately in the victim's browser even without user's intervention.

CWE-79 - Cross Site Scripting

Cross-Site Scripting, commonly referred to as XSS, is the most dominant class of vulnerabilities. It allows an attacker to inject malicious code into a pregnable web application and victimize its users. The exploitation of such a weakness can cause severe issues such as account takeover, and sensitive data exfiltration. Because of the prevalence of XSS vulnerabilities and their high rate of exploitation, it has remained in the OWASP top 10 vulnerabilities for years.
