Mocha version 3.0.0 represents a notable update from its predecessor, version 2.5.3, offering developers updated dependencies and potentially improved performance and stability, while maintaining its core function as a flexible and fun javascript testing framework. While both share the same core functionality, several key changes in the dependency structure are present. Firstly, version 3.0.0 upgrades several key dependencies, most notably glob from 3.2.11 to 7.0.5, commander from 2.3.0 to 2.9.0 and supports-color from 1.2.0 to 3.1.2. The newer release also replaces jade with lodash.create and removes to-iso-string from its dependencies and add browser-stdout and escape-string-regexp. On the tools front, version 3.0.0 upgrades eslint from ^1.2.1 to ^2.13.1, should from ~8.0.0 to ^9.0.2 and through2 from ~0.6.5 to ^2.0.1. Though subtle, these changes can have implications for developers integrating Mocha into their projects. For example, the updated glob dependency provides enhanced file matching capabilities, potentially simplifying test setup and execution. The updated commander brings improved command-line argument parsing. Additionally, the removal of jade as a dependency suggests a shift away from that templating engine, potentially impacting users who relied on it within their tests. Developers should carefully review the updated dependencies to ensure compatibility with their existing toolchains and leverage the new features and deprecations.
All the vulnerabilities related to the version 3.0.0 of the package
Regular Expression Denial of Service (ReDoS)
A vulnerability was found in diff before v3.5.0, the affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) attacks.
debug Inefficient Regular Expression Complexity vulnerability
A vulnerability classified as problematic has been found in debug-js debug up to 3.0.x. This affects the function useColors of the file src/node.js. The manipulation of the argument str leads to inefficient regular expression complexity. Upgrading to version 3.1.0 is able to address this issue. The name of the patch is c38a0166c266a679c8de012d4eaccec3f944e685. It is recommended to upgrade the affected component. The identifier VDB-217665 was assigned to this vulnerability. The patch has been backported to the 2.6.x branch in version 2.6.9.
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.
Vercel ms Inefficient Regular Expression Complexity vulnerability
A vulnerability, which was classified as problematic, has been found in vercel ms up to 1.x. This issue affects the function parse of the file index.js. The manipulation of the argument str leads to inefficient regular expression complexity. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 2.0.0 is able to address this issue. The name of the patch is caae2988ba2a37765d055c4eee63d383320ee662. It is recommended to upgrade the affected component. The associated identifier of this vulnerability is VDB-217451.
Growl before 1.10.0 vulnerable to Command Injection
Affected versions of growl do not properly sanitize input prior to passing it into a shell command, allowing for arbitrary command execution.
Update to version 1.10.0 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).
