Babel-core versions 4.7.11 and 4.7.10 are closely related iterations of a vital tool for JavaScript developers, designed to transform modern ES6 code into widely compatible ES5. Both versions share the core functionality of enabling developers to utilize the latest JavaScript features while ensuring their code runs smoothly across older browsers and environments. The primary function remains consistent: converting cutting-edge JavaScript into a more universally understood format, complete with source maps for easier debugging.
A detailed comparison reveals almost identical dependency lists, indicating that the core components and underlying libraries powering these versions are largely the same. Each relies on a suite of packages like acorn-babel for parsing, ast-types for AST manipulation, and regenerator-babel for generator function support. The versions also share a common thread in utilizing tools like chalk for terminal styling, commander for command-line interface creation, and lodash for utility functions.
The most discernible difference surfaces when considering the release dates. Version 4.7.11 came out just a short time after. 4.7.10. This suggests that 4.7.11 likely includes minor bug fixes, performance enhancements, or very targeted updates that don't necessitate substantial changes in dependencies. For developers already using 4.7.10, upgrading to 4.7.11 promises a potentially more refined experience with minimal disruption, ensuring they continue to leverage the advantages of Babel's code transformation capabilities seamlessly. The upgrade is probably minimal but recommended to get the best version.
All the vulnerabilities related to the version 4.7.11 of the package
Prototype Pollution in lodash
Versions of lodash before 4.17.12 are vulnerable to Prototype Pollution. The function defaultsDeep allows a malicious user to modify the prototype of Object via {constructor: {prototype: {...}}} causing the addition or modification of an existing property that will exist on all objects.
Update to version 4.17.12 or later.
Prototype Pollution in lodash
Versions of lodash before 4.17.5 are vulnerable to prototype pollution.
The vulnerable functions are 'defaultsDeep', 'merge', and 'mergeWith' which allow a malicious user to modify the prototype of Object via __proto__ causing the addition or modification of an existing property that will exist on all objects.
Update to version 4.17.5 or later.
Prototype Pollution in lodash
Versions of lodash before 4.17.11 are vulnerable to prototype pollution.
The vulnerable functions are 'defaultsDeep', 'merge', and 'mergeWith' which allow a malicious user to modify the prototype of Object via {constructor: {prototype: {...}}} causing the addition or modification of an existing property that will exist on all objects.
Update to version 4.17.11 or later.
Regular Expression Denial of Service (ReDoS) in lodash
lodash prior to 4.7.11 is affected by: CWE-400: Uncontrolled Resource Consumption. The impact is: Denial of service. The component is: Date handler. The attack vector is: Attacker provides very long strings, which the library attempts to match using a regular expression. The fixed version is: 4.7.11.
Prototype Pollution in lodash
Versions of lodash prior to 4.17.19 are vulnerable to Prototype Pollution. The functions pick, set, setWith, update, updateWith, and zipObjectDeep allow a malicious user to modify the prototype of Object if the property identifiers are user-supplied. Being affected by this issue requires manipulating objects based on user-provided property values or arrays.
This vulnerability causes the addition or modification of an existing property that will exist on all objects and may lead to Denial of Service or Code Execution under specific circumstances.
Regular Expression Denial of Service (ReDoS) in lodash
All versions of package lodash prior to 4.17.21 are vulnerable to Regular Expression Denial of Service (ReDoS) via the toNumber, trim and trimEnd functions.
Steps to reproduce (provided by reporter Liyuan Chen):
var lo = require('lodash');
function build_blank(n) {
var ret = "1"
for (var i = 0; i < n; i++) {
ret += " "
}
return ret + "1";
}
var s = build_blank(50000) var time0 = Date.now();
lo.trim(s)
var time_cost0 = Date.now() - time0;
console.log("time_cost0: " + time_cost0);
var time1 = Date.now();
lo.toNumber(s) var time_cost1 = Date.now() - time1;
console.log("time_cost1: " + time_cost1);
var time2 = Date.now();
lo.trimEnd(s);
var time_cost2 = Date.now() - time2;
console.log("time_cost2: " + time_cost2);
Command Injection in lodash
lodash versions prior to 4.17.21 are vulnerable to Command Injection via the template function.
