Mocha 8.1.1, a minor release following closely on the heels of 8.1.0, continues to build upon the foundation of this popular and versatile JavaScript testing framework. Both versions maintain the core principle of providing a simple yet flexible environment for test-driven development, suitable for both Node.js and browser environments. The dependency trees for both are nearly identical, featuring essential tools like he for HTML entity encoding, ms for human-readable time spans, diff for detailed comparisons, and yargs for command-line argument parsing. Developers leveraging Mocha for their testing workflows will find a familiar landscape in both versions.
Primarily, the most notable difference arises in the dist section, where unpackedSize and releaseDate attributes vary slightly, with Mocha 8.1.1 being a newer release with a potentially higher unpacked size. While the core functionality and API surface likely remain consistent, this minor release could incorporate bug fixes, performance enhancements, or refinements that address specific edge cases or improve overall stability. For developers already using Mocha 8.1.0, upgrading to 8.1.1 is generally recommended to benefit from the latest improvements and ensure compatibility. For new users, choosing the latest version is always a good practice. The package's robust suite of devDependencies, including tools for linting (eslint), code coverage (nyc), mocking (sinon), and browser testing (karma), remains consistent ensuring high standards for code quality and testability.
All the vulnerabilities related to the version 8.1.1 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. It is recommended to upgrade the affected component. The identifier VDB-216777 was assigned to this vulnerability.
