Babel-core versions 4.7.13 and 4.7.14 are minor releases in the history of this crucial JavaScript transpiler, designed to convert modern ES6 code into widely compatible ES5. Both versions share the same core functionality, enabling developers to leverage new JavaScript features while ensuring their code runs smoothly on older browsers and environments. They both rely on a suite of dependencies for parsing, code manipulation, and source map generation. These include acorn-babel for ES6 parsing, ast-types for working with Abstract Syntax Trees, and source-map for debugging.
A key highlight is the consistent set of dependencies, indicating a focus on stability and incremental improvements. Developers can expect a familiar environment when upgrading from 4.7.13 to 4.7.14.
The primary difference lies in the release date, with version 4.7.14 being released just a day after 4.7.13. This suggests that 4.7.14 is likely a patch release addressing minor bugs, dependency updates, or performance tweaks identified in the previous version. While specific changes are not detailed in the metadata, developers are often advised to upgrade to the latest patch releases for bug fixes.
For developers utilizing babel-core, these versions offer a robust solution for ES6 transpilation with source map support, easing debugging in older environments. The consistent dependency list across versions underscores the stability of the core functionality, making upgrades less risky. If you're targeting broad browser support, these versions provide a reliable pathway to using modern JavaScript syntax in your projects. Consider upgrading to the latest version for the the latest bug fixes.
All the vulnerabilities related to the version 4.7.14 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.
