Babel-core, a cornerstone for JavaScript developers, facilitates seamless ES6 to ES5 transpilation, ensuring code compatibility across diverse environments. Versions 4.5.3 and 4.5.4 offer this essential functionality with minimal discernible differences in declared dependencies. Both versions rely upon a robust set of supporting libraries, including acorn-babel for AST parsing, ast-types for AST node manipulation, chalk for stylized console output, and commander for command-line interface creation. Core-js provides polyfills for modern JavaScript features, while debug aids in development troubleshooting. Lodash offers utility functions, and source-map and source-map-support are present for easier debugging when working with compiled code.
The key distinction lies in the release date with version 4.5.4 timestamped just twelve minutes later than 4.5.3. This proximity suggests that version 4.5.4 is likely a patch release, potentially addressing minor bugs or edge-case scenarios uncovered in version 4.5.3. While the dependency lists remain identical, internal improvements or bug fixes could have been implemented.
For developers, the choice between versions may depend on their risk tolerance and any specific issues encountered with 4.5.3 the update to 4.5.4 appears to be a low-risk upgrade boasting a tiny improvement for legacy ECMAScript code. Keeping up with the latest patches allows developers to benefit from any refinements. However, reviewing the specific commit logs between the two versions on the Babel GitHub repository is advisable for a comprehensive understanding of the changes.
All the vulnerabilities related to the version 4.5.4 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.
