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::API - (DEPRECATED) An OpenAPI REST controller for the Yancy editor

VERSION

version 1.088

DESCRIPTION

DEPRECATED: This module has been merged into the Yancy::Controller::Yancy class and the editor now uses that class by default.

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

METHODS

list

List the items in a schema. The schema name should be in the stash key schema.

Each returned item will be filtered by filters conforming with "yancy.filter.add" in Mojolicious::Plugin::Yancy that are passed in the array-ref in stash key filters_out.

$limit, $offset, and $order_by may be provided as query parameters.

get

Get a single item from a schema. The schema should be in the stash key schema.

The item's ID field-name is in the stash key id_field. The ID itself is extracted from the OpenAPI input, under a parameter of that name.

The return value is filtered like each result is in "list".

set

Create or update an item in a schema. The schema should be in the stash key schema.

The item to be updated is determined as with "get", if any. The new item is extracted from the OpenAPI input, under parameter name newItem, and must be a hash/JSON "object". It will be filtered by filters conforming with "yancy.filter.add" in Mojolicious::Plugin::Yancy that are passed in the array-ref in stash key filters, after the schema and property filters have been applied.

The return value is filtered like each result is in "list".

delete

Delete an item from a schema. The schema name should be in the stash key schema.

The item to be deleted is determined as with "get".

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 Yancy::Controller::Yancy and override the desired methods to provide the desired functionality.

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

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

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