Mocha 8.1.3 is a minor release of the popular JavaScript test framework, building upon the solid foundation of version 8.1.2. A primary difference lies within the updated development dependencies, reflecting the continuous evolution of the tooling ecosystem. Specifically, @mocha/docdash sees an update, moving from version 3.0.0 in 8.1.2 to version 3.0.1 in 8.1.3. This likely incorporates improvements or bug fixes within the documentation generation process. Additionally, the fail-on-errors-webpack-plugin moves to version ^3.0.0 from not existing in devDependencies in 8.1.2. This ensures that any webpack compilation errors during development or building processes will halt execution, encouraging rigorous code quality and proper configuration. The file count in the distribution also increases from 73 to 74, potentially signifying a new file included for the updated version. The slight increase in unpacked size from 2685685 bytes to 2690545 bytes further supports this theory.
For developers, these changes mostly represent incremental improvements in the development workflow. The core testing functionality of Mocha remains consistent between these two versions, offering the same simple, flexible, and enjoyable testing experience. The updated docdash version could lead to improved documentation accessibility and clarity, while the new fail-on-errors-webpack-plugin helps catch build errors earlier. Upgrading from 8.1.2 to 8.1.3 will primarily benefit those who rely on the latest development tools and want to ensure a robust and error-free development environment. Overall, version 8.1.3 signifies a commitment to maintaining an up-to-date and dependable test framework for JavaScript developers.
All the vulnerabilities related to the version 8.1.3 of the package
Regular Expression Denial of Service in debug
Affected versions of debug are vulnerable to regular expression denial of service when untrusted user input is passed into the o formatter.
As it takes 50,000 characters to block the event loop for 2 seconds, this issue is a low severity issue.
This was later re-introduced in version v3.2.0, and then repatched in versions 3.2.7 and 4.3.1.
Version 2.x.x: Update to version 2.6.9 or later. Version 3.1.x: Update to version 3.1.0 or later. Version 3.2.x: Update to version 3.2.7 or later. Version 4.x.x: Update to version 4.3.1 or later.
minimatch ReDoS vulnerability
A vulnerability was found in the minimatch package. This flaw allows a Regular Expression Denial of Service (ReDoS) when calling the braceExpand function with specific arguments, resulting in a Denial of Service.
flat vulnerable to Prototype Pollution
flat helps flatten/unflatten nested Javascript objects. A vulnerability, which was classified as critical, was found in hughsk flat up to 5.0.0. This affects the function unflatten of the file index.js. The manipulation leads to improperly controlled modification of object prototype attributes ('prototype pollution'). It is possible to initiate the attack remotely. Upgrading to version 5.0.1 can address this issue. The name of the patch is 20ef0ef55dfa028caddaedbcb33efbdb04d18e13.
