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.

Get started with the Yancy documentation!

This file documents the application base class. You can use this class directly via the yancy command, or you can extend this class to build your own app.

Starting Your Own Yancy Application

If you have an existing Mojolicious application you want to add Yancy to, see Mojolicious::Plugin::Yancy.

The base Yancy class exists to provide a way to rapidly prototype a data-driven web application. Apps that inherit from Yancy get these features out-of-the-box:

If you're familiar with developing Mojolicious applications, you can start from the app skeleton at https://github.com/preaction/Yancy/tree/master/eg/skeleton.

To begin writing a new application from scratch, create a lib directory and add a MyApp.pm file that extends the Yancy class:

package MyApp;
use Mojo::Base 'Yancy', -signatures;

As in any other Mojolicious app, add your routes, plugins, and other setup to the startup method. Don't forget to call Yancy's "startup" method!

sub startup( $self ) {
    $self->SUPER::startup;
    # ... Add your routes and other setup here
}

Next, create a configuration file named my_app.conf to connect to your database:

{
    backend => 'sqlite:my_app.db',
}

Last, create a simple application script named script/my_app to start your application:

#!/usr/bin/env perl

use Mojo::Base -strict;
use lib qw(lib);
use Mojolicious::Commands;

# Start command line interface for application
Mojolicious::Commands->start_app('MyApp');

Now you can run ./script/my_app daemon to start your app!

To make developing your app easy and fun, make sure you're familiar with these guides:
