@storybook/addon-essentials is a collection of essential Storybook addons designed to enhance the development experience and provide commonly used features out-of-the-box. Versions 5.3.12 and 5.3.13 offer a curated selection of tools to streamline UI development and testing, including addon-viewport for responsive design testing and addon-backgrounds for visualizing components against different backgrounds. Both versions share the same core dependencies like ts-dedent for template literal manipulation and peer dependencies of react, react-is, and babel-loader to ensure compatibility with standard React setups.
The key difference between these versions lies in the internal dependencies on other Storybook packages: @storybook/api, @storybook/addons, and @storybook/node-logger. Version 5.3.13 bumps these dependencies to their respective 5.3.13 versions, whereas 5.3.12 relies on the 5.3.12 versions. This means that version 5.3.13 incorporates any bug fixes, performance improvements, or new features introduced in those core Storybook packages between the two releases.
For developers, upgrading from 5.3.12 to 5.3.13 promises access to the latest refinements within the Storybook ecosystem. The update ensures smoother integration and potentially resolves any issues present in the older versions of the dependent packages. If you are using storybook, it is recommended to update to the latest patch version to take advantage of latest updates. While the unpacked size and file count remain the same for both versions, suggesting minimal architectural changes, the updated dependencies may provide a more robust and feature-complete developer experience.
All the vulnerabilities related to the version 5.3.13 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.
