jquery prior to 1.9.0 allows Cross-site Scripting attacks via the load method
CVE-2020-7656
6.1 - Medium
- May 19, 2020
jquery prior to 1.9.0 allows Cross-site Scripting attacks via the load method. 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.
XSS
In jQuery versions greater than or equal to 1.2 and before 3.5.0, passing HTML
CVE-2020-11022
6.1 - Medium
- April 29, 2020
In jQuery versions greater than or equal to 1.2 and before 3.5.0, 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. This problem is patched in jQuery 3.5.0.
XSS
In jQuery versions greater than or equal to 1.0.3 and before 3.5.0, passing HTML containing <option> elements
CVE-2020-11023
6.1 - Medium
- April 29, 2020
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.
XSS
jQuery v2.2.2 allows XSS via a crafted onerror attribute of an IMG element
CVE-2018-18405
6.1 - Medium
- April 22, 2020
jQuery v2.2.2 allows XSS via a crafted onerror attribute of an IMG element. NOTE: this vulnerability has been reported to be spam entry
XSS
jQuery before 3.4.0, as used in Drupal, Backdrop CMS, and other products, mishandles jQuery.extend(true, {},
CVE-2019-11358
6.1 - Medium
- April 20, 2019
jQuery before 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.
Prototype Pollution
jQuery before 1.9.0 is vulnerable to Cross-site Scripting (XSS) attacks
CVE-2012-6708
6.1 - Medium
- January 18, 2018
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 the '<' character, limiting exploitability only to attackers who can control the beginning of a string, which is far less common.
XSS
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
CVE-2015-9251
6.1 - Medium
- January 18, 2018
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.
XSS
jQuery 3.0.0-rc.1 is vulnerable to Denial of Service (DoS) due to removing a logic that lowercased attribute names
CVE-2016-10707
7.5 - High
- January 18, 2018
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.
Stack Exhaustion
The jQuery framework exchanges data using JavaScript Object Notation (JSON) without an associated protection scheme, which allows remote attackers to obtain the data via a web page
CVE-2007-2379
- April 30, 2007
The jQuery framework exchanges data using JavaScript Object Notation (JSON) without an associated protection scheme, which allows remote attackers to obtain the data via a web page that retrieves the data through a URL in the SRC attribute of a SCRIPT element and captures the data using other JavaScript code, aka "JavaScript Hijacking."
