Mocha version 6.2.3 represents a minor update over its predecessor, 6.2.2, within this popular JavaScript test framework. While the core functionality remains consistent – providing a versatile and enjoyable testing experience – several dependency adjustments distinguish the two versions. A notable change lies in the updated yargs dependency, moving from version 13.3.0 to 13.3.2. This likely addresses bug fixes or minor enhancements within the argument parsing library. Another updated dependency is yargs-parser which moved from 13.1.1 to 13.1.2.
The mocha package enables developers to write flexible and maintainable tests. The framework supports various assertion libraries beyond its built-in ones, facilitating integration into existing workflows. Developers benefit from the flexibility to tailor the test suite using a variety of reporters, as well as customization options, suiting individual preferences and project needs. The use of popular dependencies such as glob makes it easy to find test files, and js-yaml offers flexible ways to configure the test environment. These changes, though seemingly incremental, contribute to a potentially more robust and reliable testing environment. The difference in unpacked size (994991 versus 993172 bytes) suggests that version 6.2.3 contains some additional features compared to 6.2.2. Developers should review the release notes to understand the precise nature of the changes and to determine whether to update, especially when working in a team where consistent dependency management is paramount.
All the vulnerabilities related to the version 6.2.3 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. It is recommended to upgrade the affected component. The identifier VDB-216777 was assigned to this vulnerability.
