Browserify version 3.24.3 represents a minor update over its predecessor, version 3.24.2, primarily focusing on internal dependency adjustments. While the core functionality remains consistent, developers should note the updated dependency versions, particularly the jump in insert-module-globals from version 2.3.0 to version 3.0.0. This specific update within the dependency tree might bring subtle changes in how Browserify handles global variables within modules. Other listed dependencies remain either unchanged or involve minor version bumps (3.24.3 contains the updated versions), which are typically bug fixes and performance improvements.
For developers, it's crucial to examine insert-module-globals for any potential impact on existing projects, especially regarding global variable handling and scope within Browserify bundles. It is always advisable to review changelogs of updated dependencies of complex packages like Browserify to ensure compatibility. These updates may involve changes to Browserify's internal workings that influence bundle sizes, execution speed, or overall project behavior. The releaseDate also indicates that version 3.24.3 came out one day after 3.24.2, so it is probably a bugfix or small update regarding recent changes, and this makes the update of insert-module-globals even more important, as it was probably related to that. Consider running thorough testing to confirm smooth integration and catch any unexpected behavior stemming from the dependency updates. Browserify continues to offer a reliable solution for bundling Node.js-style modules for browser deployment.
All the vulnerabilities related to the version 3.24.3 of the package
Regular Expression Denial of Service in uglify-js
Versions of uglify-js prior to 2.6.0 are affected by a regular expression denial of service vulnerability when malicious inputs are passed into the parse() method.
var u = require('uglify-js');
var genstr = function (len, chr) {
var result = "";
for (i=0; i<=len; i++) {
result = result + chr;
}
return result;
}
u.parse("var a = " + genstr(process.argv[2], "1") + ".1ee7;");

Update to version 2.6.0 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).
Potential Command Injection in shell-quote
Affected versions of shell-quote do not properly escape command line arguments, which may result in command injection if the library is used to escape user input destined for use as command line arguments.
The following characters are not escaped properly: >,;,{,}
Bash has a neat but not well known feature known as "Bash Brace Expansion", wherein a sub-command can be executed without spaces by running it between a set of {} and using the , instead of to seperate arguments. Because of this, full command injection is possible even though it was initially thought to be impossible.
const quote = require('shell-quote').quote;
console.log(quote(['a;{echo,test,123,234}']));
// Actual "a;{echo,test,123,234}"
// Expected "a\;\{echo,test,123,234\}"
// Functional Equivalent "a; echo 'test' '123' '1234'"
Update to version 1.6.1 or later.
Potential for Script Injection in syntax-error
Versions of syntax-error prior to 1.1.1 are affected by a cross-site scripting vulnerability which may allow a malicious file to execute code when browserified.
Update to version 1.1.1 or later.
