@storybook/addon-essentials, a suite of essential addons designed to enhance the Storybook development experience, saw a minor version update from 5.3.6 to 5.3.7. Both versions offer the same core functionality: a curated set of addons, including addon-viewport and addon-backgrounds, providing developers with tools for responsive design testing and background customization directly within their Storybook environment. They share the same dependencies, such as ts-dedent for cleaner template literals and core Storybook packages like @storybook/api, @storybook/addons, and @storybook/node-logger, ensuring a consistent integration within the Storybook ecosystem. Development dependencies, crucial for contributing to the project or running tests, remain the same with @types/jest.
Similarly, peer dependencies specify the required versions of react, react-is, and babel-loader, underscoring compatibility needs. Both packages are released under the MIT license and are maintained within the Storybook repository on GitHub.
The key difference lies primarily in the version numbers of the internal Storybook dependencies. Version 5.3.7 updates those internal dependencies (@storybook/api, @storybook/addons, @storybook/node-logger, @storybook/addon-viewport, @storybook/addon-backgrounds) to version 5.3.7. This suggests the update likely includes bug fixes, performance improvements, or minor feature enhancements within those core Storybook modules. Developers should upgrade to 5.3.7 to benefit from these potential improvements and ensure they are running the most up-to-date and stable version of the essentials addon package. The release date differential also reflects the recency of 5.3.7 and therefore it is the version that is better to use.
All the vulnerabilities related to the version 5.3.7 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.
