Babel-core version 4.4.6 represents a minor update over its preceding stable release, version 4.4.5, in the evolution of this crucial JavaScript transpiler. Both versions share the core functionality of converting ES6 (ECMAScript 2015) code into more widely compatible ES5, ensuring broader browser support and facilitating the adoption of newer JavaScript features. The descriptions for both versions are identical, highlighting this key capability.
Examining the dependencies reveals the nuanced changes between these releases. The most notable difference lies in the updated versions of core-js and chalk. Core-js sees an upgrade from version 0.5.4 to version 0.6.1, suggesting improved polyfilling capabilities and expanded support for various ES6 features. Chalk, a popular terminal styling library, jumps from version 0.5.1 to version 1.0.0, indicating potential enhancements in console output formatting and color support. Additionally, regenerator-babel advances from version 0.8.10-2 to 0.8.13-1, suggesting improvements in asynchronous code transformation using generators. Developers should take into account these dependency updates as they might influence the project's compatibility and feature set. While the core functionality remains consistent, the updated dependencies in version 4.4.6 provide developers with enhanced tools and potentially more robust handling of modern JavaScript syntax, making it a worthwhile upgrade for those seeking the latest improvements in Babel's ES6-to-ES5 transformation capabilities. The babel-core package, at its essence, allows a smoother transition to modern Javascript.
All the vulnerabilities related to the version 4.4.6 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.
