Security Advisories (9)
CVE-2020-11022 (2020-04-29)

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.

CVE-2020-11023 (2020-04-29)

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.

CVE-2019-11358 (2019-04-20)

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.

CVE-2015-9251 (2018-01-18)

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.

CVE-2011-4969 (2013-03-08)

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.

CVE-2012-6708 (2018-01-18)

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.

CVE-2020-7656 (2020-05-19)

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.

CVE-2019-5428

Prototype Pollution is a vulnerability affecting JavaScript. Prototype Pollution refers to the ability to inject properties into existing JavaScript language construct prototypes, such as objects. JavaScript allows all Object attributes to be altered, including their magical attributes such as _proto_, constructor and prototype. An attacker manipulates these attributes to overwrite, or pollute, a JavaScript application object prototype of the base object by injecting other values. Properties on the Object.prototype are then inherited by all the JavaScript objects through the prototype chain. When that happens, this leads to either denial of service by triggering JavaScript exceptions, or it tampers with the application source code to force the code path that the attacker injects, thereby leading to remote code execution.

CVE-2014-6071 (2018-01-16)

jQuery 1.4.2 allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to use of the text method inside after.

NAME

Squatting::Mapper - map requests to session queues

DESCRIPTION

The purpose of this module is to be on the lookout for requests that should get special treatment by Continuity. This is usually done by giving your controller a continuity attribute and setting it to a true value:

C(
  Events => [ '/@events/(\d+)' ],

  get => sub {
    my ($self, $rand) = @_;
    my $cr = $self->cr;
    while (1) {           # <--- COMET event loops typically loop forever
      # broadcasting relevant events
      # to long-polling HTTP requests
      # as they come in...
      $cr->next;
    }
  },

  continuity => 1,        # <--- causes Squatting::Mapper to notice
)

When it sees that continuity is true, the request will be given a session id based on: $cookie_session + $app_name + $controller_name + $path. Normally, it's just $cookie_session, but when you get these extra pieces added to your session id, that tells Continuity that you want to have a separate coroutine for this request.

The primary intended use for handling requests in a separate coroutine is to facilitate COMET event loops. When a user visits a COMET-enabled site, there will be some JavaScript that starts a long-polling HTTP request. On the server-side, the long-polling handler will typically have an infinite loop in it, so it needs to sit off in its own coroutine so that it doesn't affect the coroutine that is handling the normal, RESTful requests.

If the user decides to open multiple-tabs to the same COMET-enabled site, each of those tabs needs to be differentiated on the server-side as well. That's when it becomes useful to stick something random in the path. Notice in the example that the path regex is '/@events/(\d+)'.

It would be the job of the JavaScript to append a random string of digits to the end of an '/@events/(\d+)' URL before starting the long-poll request. That'll let Squatting::Mapper give each tab its own coroutine as well.
