The jQuery googleslides plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'googleslides' shortcode in all versions up to, and including, 1.3. This is due to insufficient input sanitization and output escaping on user supplied attributes (userid, albumid, authkey, imgmax, maxresults, random, caption, albumlink, time, and fadespeed) in the googleslideshandler() function, which interpolates the attribute values directly into single-quoted HTML attributes without using escattr(). This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The jQuery Colorbox WordPress plugin through 4.6.3 uses the colorbox library, which does not sanitize title attributes on links before using them, allowing users with at least the contributor role to conduct XSS attacks against administrators.

An unrestricted file upload vulnerability exists in BuilderEngine 3.5.0 via the integration of the elFinder 2.0 file manager and its use of the jQuery File Upload plugin. The plugin fails to properly validate or restrict file types or locations during upload operations, allowing an attacker to upload a malicious .php file and subsequently execute arbitrary PHP code on the server under the context of the web server process. While the root vulnerability lies within the jQuery File Upload component, BuilderEngine’s improper integration and lack of access controls expose this functionality to unauthenticated users, resulting in full remote code execution.

Versions of the package jquery-validation before 1.20.0 are vulnerable to Cross-site Scripting (XSS) in the showLabel() function, which may take input from a user-controlled placeholder value. This value will populate a message via $.validator.messages in a user localizable dictionary.

Cross Site Scripting vulnerability in JavaScript Library jquery-ui v.1.13.1 allows a remote attacker to obtain sensitive information and execute arbitrary code via a crafted payload to the window.addEventListener component. NOTE: this is disputed by the Supplier because it cannot be reproduced, and because the exploitation example does not indicate whether, or how, the example website is using jQuery UI.

Under certain circumstances the camera may be susceptible to known vulnerabilities associated with the JQuery versions prior to 3.5.0 third-party component

The jQuery T(-) Countdown Widget plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's tminus shortcode in all versions up to, and including, 2.3.25 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. CVE-2024-37247 may be a duplicate of this issue.

Original Description

Cross Site Scripting vulnerability in jQuery v.2.2.0 until v.3.5.0 allows a remote attacker to execute arbitrary code via the <options> element.

jQuery-UI is the official jQuery user interface library. Prior to version 1.13.0, accepting the value of the of option of the .position() util from untrusted sources may execute untrusted code. The issue is fixed in jQuery UI 1.13.0. Any string value passed to the of option is now treated as a CSS selector. A workaround is to not accept the value of the of option from untrusted sources.

jQuery-UI is the official jQuery user interface library. Prior to version 1.13.0, accepting the value of various Text options of the Datepicker widget from untrusted sources may execute untrusted code. The issue is fixed in jQuery UI 1.13.0. The values passed to various Text options are now always treated as pure text, not HTML. A workaround is to not accept the value of the Text options from untrusted sources.

The jQuery project released version 3.5.0, and as part of that, disclosed two security vulnerabilities that affect all prior versions. As mentioned in the jQuery blog, both are [...] security issues in jQuery’s DOM manipulation methods, as in .html(), .append(), and the others. Security advisories for both of these issues have been published on GitHub. Those advisories are:

CVE-2020-11022

CVE-2020-11023

These vulnerabilities may be exploitable on some Drupal sites. This Drupal security release backports the fixes to the relevant jQuery functions, without making any other changes to the jQuery version that is included in Drupal core or running on the site via some other module such as jQuery Update. It is not necessary to update jqueryupdate on Drupal 7 sites that have the module installed. Backwards-compatibility code has also been added to minimize regressions to Drupal sites that might rely on jQuery's prior behavior. With jQuery 3.5, incorrect self-closing HTML tags in JavaScript for elements where end tags are normally required will encounter a change in what jQuery returns or inserts. To minimize that disruption in 8.8.x and earlier, this security release retains jQuery's prior behavior for most safe tags. There may still be regressions for edge cases, including invalidly self-closed custom elements on Internet Explorer. (Note: the backwards compatibility layer will not be included in the upcoming Drupal 8.9 and 9.0 releases, so Drupal 8 and 9 modules, themes, and sites should correct tags in JavaScript to properly use closing tags.) If you find a regression caused by the jQuery changes, please report it in Drupal core's issue queue (or that of the relevant contrib project). However, if you believe you have found a security issue, please report it privately to the Drupal Security Team.

A flaw was found in jquery in versions prior to 1.9.0. A cross-site scripting attack is possible as the load method fails to recognize and remove "<script>" HTML tags that contain a whitespace character which results in the enclosed script logic to be executed. The highest threat from this vulnerability is to data confidentiality and integrity.

Impact Passing HTML containing <option> elements from untrusted sources - even after sanitizing them - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code.

Patches This problem is patched in jQuery 3.5.0.

Workarounds To workaround this issue without upgrading, use DOMPurify with its SAFEFORJQUERY option to sanitize the HTML string before passing it to a jQuery method.

Workarounds To workaround the issue without upgrading, adding the following to your code:

js jQuery.htmlPrefilter = function( html ) { return html; };

You need to use at least jQuery 1.12/2.2 or newer to be able to apply this workaround.

DISPUTED 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.

A Prototype Pollution vulnerability was found in jquery. Untrusted JSON passed to the extend function could lead to modifying objects up the prototype chain, including the global Object. A crafted JSON object passed to a vulnerable method could lead to denial of service or data injection, with various consequences.

Affected versions of jquery are vulnerable to cross-site scripting. This occurs because the main jquery function uses a regular expression to differentiate between HTML and selectors, but does not properly anchor the regular expression. The result is that jquery may interpret HTML as selectors when given certain inputs, allowing for client side code execution.

Proof of Concept $("#log").html( $("element[attribute='<img src=\"x\" onerror=\"alert(1)\" />']").html() );

Recommendation

Update to version 1.9.0 or later.

Affected versions of jquery use a lowercasing logic on attribute names. When given a boolean attribute with a name that contains uppercase characters, jquery enters into an infinite recursion loop, exceeding the call stack limit, and resulting in a denial of service condition.

Recommendation

Update to version 3.0.0 or later.

Affected versions of jquery interpret text/javascript responses from cross-origin ajax requests, and automatically execute the contents in jQuery.globalEval, even when the ajax request doesn't contain the dataType option.

Recommendation

Update to version 3.0.0 or later.

Cross-site scripting (XSS) vulnerability in jquery.ui.dialog.js in the Dialog widget in jQuery UI before 1.10.0 allows remote attackers to inject arbitrary web script or HTML via the title option.

A cross-site scripting flaw was reported against jQuery 1.4.2:

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.

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."
