Security Advisories (12)
CVE-2018-14041 (2018-07-13)

In Bootstrap before 4.1.2, XSS is possible in the data-target property of scrollspy.

CVE-2018-14042 (2018-07-13)

In Bootstrap before 4.1.2, XSS is possible in the data-container property of tooltip.

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

yatt_lite README -- Introduction to YATT::Lite

DESCRIPTION

YATT is Yet Another Template Toolkit, aimed at Web Designers, rather than well-trained programmers. To achieve this goal, YATT has following characteristics:

  • More readable syntax for HTML/XML savvy designers.

  • Various supports to build up reusable templates(widgets).

  • Static syntax checking via lint.

  • Typed variable for automatic html escaping to avoid XSS.

  • Extended entity syntax to embed complex things cleanly.

YATT::Lite は YATT と構文の上位互換性をほぼ保ちつつ高速化し、 あわせて拡張性も向上させた、全面改訂版です。 将来的に YATT::Lite が十分に安定した段階で、これを次の YATT とする予定です。

以下、一連のマニュアルで、一般名としての YATT::Lite を yatt_lite、 又は単に yatt と表記します。

Next Steps

練習環境を作るには

実際に yatt を動かしながら勉強した方が身につき易いので、誰かに頼むか自力で yl_psgi_setup を読んで、 yatt を動かせる環境を setup することをお勧めします。

デザイナーの場合

yatt の書き方を勉強するには yl_designers_intro から始めてください。

プログラマーの場合

  • YATT::Lite を Web Framework として使う場合や、他の Web Framework から PSGI 経由で使う場合は yl_webprogramming_intro をお読み下さい。

  • YATT::Lite の Core を perl からモジュールとして活用するための基礎は yl_programmers_intro をお読み下さい。

Web サーバー管理者の場合

yatt_lite のインストール方法に関しては setup_apache を参照してください。
