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

Yancy::Controller::Yancy - A simple REST controller for Mojolicious

VERSION

version 0.010

DESCRIPTION

This module contains the routes that Yancy uses to work with the backend data. This API is used by the web application.

METHODS

list_items

List the items in a collection. The collection name should be in the stash key collection. limit, offset, and order_by may be provided as query parameters.

add_item

Add a new item to the collection. The new item should be in the request body as JSON. The collection name should be in the stash key collection.

get_item

Get a single item from a collection. The collection should be in the stash key collection, and the item's ID in the stash key id.

set_item

Update an item in a collection. The collection should be in the stash key collection, and the item's ID in the stash key id. The updated item should be in the request body as JSON.

delete_item

Delete an item from a collection. The collection name should be in the stash key collection. The ID of the item should be in the stash key id.

SUBCLASSING

To change how the API provides access to the data in your database, you can create a custom controller. To do so, you should extend this class and override the desired methods to provide the desired functionality.

package MyApp::Controller::CustomYancy;
use Mojo::Base 'Yancy::Controller::Yancy';
sub list_items {
    my ( $c ) = @_;
    return unless $c->openapi->valid_input;
    my $items = $c->yancy->backend->list( $c->stash( 'collection' ) );
    return $c->render(
        status => 200,
        openapi => $items,
    );
}

package main;
use Mojolicious::Lite;
push @{ app->routes->namespaces }, 'MyApp::Controller';
plugin Yancy => {
    controller_class => 'CustomYancy',
};

For an example, you could extend this class to add authorization based on your own requirements.
