CVE-2020-11023
Potential XSS vulnerability in jQuery
What it is
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.
CISA: JQuery contains a persistent cross-site scripting (XSS) vulnerability. When passing maliciously formed, untrusted input enclosed in HTML tags, JQuery's DOM manipulators can execute untrusted code in the context of the user's browser.
What to do
Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
