@storybook/addon-essentials is a crucial package for enhancing Storybook development environments by bundling together essential addons. Comparing versions 5.3.1 and 5.3.2, the core functionality remains consistent, focusing on providing a curated set of addons to improve the Storybook experience. Both versions include dependencies like ts-dedent for template literal manipulation and core Storybook packages such as @storybook/api, @storybook/addons, and @storybook/node-logger, ensuring seamless integration within the Storybook ecosystem. Key addons bundled include @storybook/addon-viewport for responsive design testing and @storybook/addon-backgrounds for customizing the background of stories.
The devDependencies remains the same, with @types/jest enabling robust testing capabilities. The peerDependencies specify compatibility with react, react-is, and babel-loader, crucial for React-based Storybook setups. The license remains MIT, indicating permissive usage.
The primary difference lies in the versioning of dependent @storybook packages. Version 5.3.2 upgrades these internal dependencies to their corresponding 5.3.2 versions, while 5.3.1 uses 5.3.1 versions. This suggests the newer version integrates bug fixes and improvements from the core Storybook library and its constituent addons. Developers should upgrade to 5.3.2 to benefit from these potential enhancements and maintain compatibility with the latest Storybook features. The release dates also highlight the recency of 5.3.2, indicating a more up-to-date integration of the Storybook ecosystem. Ultimately, both versions provide core addon functionalities, but the updated dependencies in 5.3.2 make it the preferred choice.
All the vulnerabilities related to the version 5.3.2 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.
