@storybook/addon-actions provides developers with a powerful tool for logging actions triggered within Storybook stories, enhancing the debugging and development workflow. Comparing versions 5.3.5 and 5.3.4, the primary difference lies in the internal dependency versions of other @storybook packages like @storybook/api, @storybook/addons, @storybook/theming, @storybook/client-api, @storybook/components and @storybook/core-events. These dependencies are updated from version 5.3.4 to 5.3.5 to ensure compatibility, bug fixes, and potentially new features within the broader Storybook ecosystem. Both versions share the same core functionality, leveraging dependencies like uuid for unique ID generation, react for the UI, polished for styling utilities, and react-inspector for structured data display. fast-deep-equal optimizes object comparison for efficient change detection.
Developers using @storybook/addon-actions can easily track when actions are dispatched in their components, along with the data associated with those actions offering valuable insights into component behavior. The addon seamlessly integrates into the Storybook environment, simplifying the process of verifying that UI interactions are triggering the expected events and data transformations. By upgrading to version 5.3.5 developers benefit from the latest improvements and fixes present in the @storybook core packages, ensuring a more stable and feature-rich development experience. The update primarily addresses internal dependencies highlighting the ongoing maintenance and improvements within the Storybook project offering developers a robust and reliable action logging solution.
All the vulnerabilities related to the version 5.3.5 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.
