Mocha is a popular and flexible JavaScript test framework for Node.js and browsers, known for its simplicity and extensibility. Comparing versions 6.1.4 and 6.1.3 reveals a subtle but important update in the dependencies. Specifically, js-yaml was updated from version 3.13.0 to 3.13.1. While seemingly minor, such dependency updates often include bug fixes, performance improvements, or security patches. Developers should investigate the specific changes within js-yaml 3.13.1 to understand the potential impact on their testing environment, especially if they rely on YAML parsing within their tests or configurations.
Both versions share a rich set of dependencies and devDependencies, highlighting Mocha's comprehensive toolkit for testing. Key dependencies like glob for file matching, debug for enhanced logging, and yargs for command-line argument parsing remain consistent. The devDependencies showcase the extensive ecosystem supporting Mocha development, including tools for linting (eslint), code formatting (prettier), code coverage (nyc), and mocking (sinon, rewiremock). The presence of browser testing tools like karma and browserify also emphasizes Mocha's versatility across different JavaScript environments. The slight increase in unpackedSize in 6.1.4 might suggest minor additions or modifications beyond the js-yaml update. Upgrading between these versions should be relatively straightforward, but verifying compatibility with your existing test suite remains crucial to ensure a smooth transition.
All the vulnerabilities related to the version 6.1.4 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.
Prototype Pollution in minimist
Affected versions of minimist are vulnerable to prototype pollution. Arguments are not properly sanitized, allowing an attacker to modify the prototype of Object, causing the addition or modification of an existing property that will exist on all objects.
Parsing the argument --__proto__.y=Polluted adds a y property with value Polluted to all objects. The argument --__proto__=Polluted raises and uncaught error and crashes the application.
This is exploitable if attackers have control over the arguments being passed to minimist.
Upgrade to versions 0.2.1, 1.2.3 or later.
Prototype Pollution in minimist
Minimist prior to 1.2.6 and 0.2.4 is vulnerable to Prototype Pollution via file index.js, function setKey() (lines 69-95).
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.
yargs-parser Vulnerable to Prototype Pollution
Affected versions of yargs-parser are vulnerable to prototype pollution. Arguments are not properly sanitized, allowing an attacker to modify the prototype of Object, causing the addition or modification of an existing property that will exist on all objects.
Parsing the argument --foo.__proto__.bar baz' adds a bar property with value baz to all objects. This is only exploitable if attackers have control over the arguments being passed to yargs-parser.
Upgrade to versions 13.1.2, 15.0.1, 18.1.1 or later.
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.
