@storybook/addon-essentials is a suite of essential addons designed to enhance your Storybook development experience. Versions 5.3.6 and 5.3.5 are closely related, offering the same core functionality of curated tools that bring out the best in Storybook. Both versions provide vital dependencies such as ts-dedent for cleaner template strings, @storybook/api and @storybook/addons for seamless integration within the Storybook ecosystem, @storybook/node-logger for helpful console output, and @storybook/addon-viewport and @storybook/addon-backgrounds for responsive design testing and visual customization.
The key difference between the two lies in their internal versioning and release timing. Version 5.3.6 was released shortly after 5.3.5, suggesting it's likely a patch release addressing minor bugs or incorporating very incremental improvements. Developers using either version will enjoy the same set of core features for controlling the viewport, managing backgrounds, and benefiting from Storybook's API and addon system. The peer dependencies, react, react-is, and babel-loader, remain consistent, ensuring compatibility with existing projects using React and Babel. Upgrading from 5.3.5 to 5.3.6 should be straightforward, offering the potential for slight enhancements and bug fixes without introducing breaking changes. Given the small version difference, developers can expect a seamless transition.
All the vulnerabilities related to the version 5.3.6 of the package
Cross site scripting in markdown-to-jsx
Versions of the package markdown-to-jsx before 7.4.0 are vulnerable to Cross-site Scripting (XSS) via the src property due to improper input sanitization. An attacker can execute arbitrary code by injecting a malicious iframe element in the markdown.
ReDOS vulnerabities: multiple grammars
The Regular expression Denial of Service (ReDoS) is a Denial of Service attack, that exploits the fact that most Regular Expression implementations may reach extreme situations that cause them to work very slowly (exponentially related to input size). An attacker can then cause a program using a Regular Expression to enter these extreme situations and then hang for a very long time.
If are you are using Highlight.js to highlight user-provided data you are possibly vulnerable. On the client-side (in a browser or Electron environment) risks could include lengthy freezes or crashes... On the server-side infinite freezes could occur... effectively preventing users from accessing your app or service (ie, Denial of Service).
This is an issue with grammars shipped with the parser (and potentially 3rd party grammars also), not the parser itself. If you are using Highlight.js with any of the following grammars you are vulnerable. If you are using highlightAuto to detect the language (and have any of these grammars registered) you are vulnerable. Exponential grammars (C, Perl, JavaScript) are auto-registered when using the common grammar subset/library require('highlight.js/lib/common') as of 10.4.0 - see https://cdn.jsdelivr.net/gh/highlightjs/cdn-release@10.4.0/build/highlight.js
All versions prior to 10.4.1 are vulnerable, including version 9.18.5.
Grammars with exponential backtracking issues:
And of course any aliases of those languages have the same issue. ie: hpp is no safer than cpp.
Grammars with polynomial backtracking issues:
And again: any aliases of those languages have the same issue. ie: ruby and rb share the same ruby issues.
