CVE-2020-11023
JQuery Cross-Site Scripting (XSS) Vulnerability
Does this matter?
Known to be exploited in the wild (CISA KEV, CISA remediation deadline 13 February 2025). Treat as an emergency change: patch or isolate now, then hunt for prior compromise.
Description
In jQuery versions greater than or equal to 1.0.3 and before 3.5.0, passing HTML containing <option> elements from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code. This problem is patched in jQuery 3.5.0.
