A cross-site scripting vulnerability may be used by attackers to bypass access controls and exploit known vulnerabilities in web-based applications, their servers, or the plug-in systems on which they rely.Įxploiting one of these, attackers fold malicious content into the content being delivered from the compromised site. XSS enables attackers to inject client-side scripts into web pages viewed by other users. What is a Cross Site Scripting vulnerability?Ĭross-site scripting (XSS) is a type of computer security vulnerability typically found in web applications. With a combination of versatility and extensibility, jQuery has changed the way that millions of people write JavaScript. JQuery is a feature-rich JavaScript library that greatly simplifies JavaScript programming. It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers. It must be noted that it is unlikely that this vulnerability has been exploited on websites that are hosted by Enrega because the hosting configuration blocks Cross Site Scripting by default. As a precaution, this Drupal security release back-ports the fix to the jQuery.extend() function, without making any other changes to the jQuery version that is included in Drupal core (3.2.1 for Drupal 8 and 1.4.4 for Drupal 7). ![]() The jQuery project released version 3.4.0, and as part of that, disclosed a security vulnerability that affects all prior versions. It's possible that this vulnerability is exploitable with some Drupal modules. The updates mitigate a Cross Site Scripting vulnerability that has been identified in the jQuery library which is included with all versions of Drupal. ![]() Drupal has released a moderately critical security update for both Drupal 8 (version 8.6.15) and Drupal 7 (version 7.66).
