Cross Site Scripting vulnerability in jQuery 2.2.0 through 3.x before 3.5.0 allows a remote attacker to execute arbitrary code via the element.

Cross-site scripting (XSS) vulnerability in jQuery before 1.6.3, when using location.hash to select elements, allows remote attackers to inject arbitrary web script or HTML via a crafted tag.

jQuery before 1.9.0 is vulnerable to Cross-site Scripting (XSS) attacks. The jQuery(strInput) function does not differentiate selectors from HTML in a reliable fashion. In vulnerable versions, jQuery determined whether the input was HTML by looking for the '<' character anywhere in the string, giving attackers more flexibility when attempting to construct a malicious payload. In fixed versions, jQuery only deems the input to be HTML if it explicitly starts with …

Versions of jquery prior to 1.9.0 are vulnerable to Cross-Site Scripting. The load method fails to recognize and remove <script> HTML tags that contain a whitespace character, i.e: </script >, which results in the enclosed script logic to be executed. This allows attackers to execute arbitrary JavaScript in a victim's browser.

Passing HTML 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.

Passing HTML containing <option> elements from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods may execute untrusted code. This problem is patched in jQuery

jQuery from 1.1.4 until 3.4.0, as used in Drupal, Backdrop CMS, and other products, mishandles jQuery.extend(true, {}, …) because of Object.prototype pollution. If an unsanitized source object contained an enumerable proto property, it could extend the native Object.prototype.

jQuery 3.0.0-rc.1 is vulnerable to Denial of Service (DoS) due to removing a logic that lowercased attribute names. Any attribute getter using a mixed-cased name for boolean attributes goes into an infinite recursion, exceeding the stack call limit.

jQuery before 3.0.0 is vulnerable to Cross-site Scripting (XSS) attacks when a cross-domain Ajax request is performed without the dataType option, causing text/javascript responses to be executed.

In the scenario where an attacker might be able to control the href attribute of an anchor tag or the action attribute of a form tag that will trigger a POST action, the attacker can set the href or action to https://attacker.com (note the leading space) that will be passed to JQuery, who will see this as a same origin request, and send the user's CSRF token to the attacker …
