Lodash is a popular JavaScript utility library praised for its consistency, customization options, and performance enhancements. Comparing versions 1.0.0 and 0.10.0, both share the same core value proposition: simplifying common programming tasks. Both versions offer developers a comprehensive suite of tools for working with arrays, objects, strings, and more. The common license is MIT and the github repository url is the same, guaranteeing a stable development. The author and email are the same.
However, a key difference lies in the release date. The 1.0.0 version was published shortly after 0.10.0, indicating a rapid iteration and potentially addressing bugs or adding minor improvements quickly. While the metadata provides limited insight into the specific code-level changes, this quick release schedule often reflects an effort to stabilize the API or improve performance based on initial user feedback.
For developers choosing between the two, opting for the newer 1.0.0 generally makes sense. The later release date suggests it likely incorporates bug fixes and refinements over 0.10.0. Given Lodash's focus on reliability and performance, even subtle updates can be important. Developers should consult the official Lodash changelog for detailed information about the specific changes included in version 1.0.0 to understand the version differences and ensure smooth integration into their projects, although they're not included in this data.
All the vulnerabilities related to the version 1.0.0 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.
