Lodash version 0.7.0 builds upon the robust foundation established by its predecessor, version 0.6.1, continuing its mission as a high-performance, feature-rich alternative to Underscore.js. Both versions offer developers a drop-in replacement, promising enhanced speed, bug fixes, and a wider array of utility functions for streamlined JavaScript development.
While the core value proposition remains the same, the upgrade from 0.6.1 to 0.7.0 signifies an incremental improvement focusing on refining the library's capabilities and addressing any identified issues. Developers can expect subtle performance optimizations, potentially impacting the execution speed of Lodash's functions in various scenarios. Furthermore, version 0.7.0 likely incorporates bug fixes discovered in the previous iteration, ensuring a more stable and reliable experience.
For developers considering Lodash, either version provides a powerful toolkit for manipulating arrays, objects, strings, and more. The emphasis on performance makes it a solid choice for applications demanding efficiency, while the extensive function library reduces the need for custom implementations. The specific advantage of choosing 0.7.0 lies in its potentially improved stability and performance enhancements over 0.6.1, making it the preferred option for new projects or when upgrading existing codebases. Always consult the changelog for detailed specifics on the improvements between versions.
All the vulnerabilities related to the version 0.7.0 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.
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.
