Lodash version 0.8.1 represents a minor iteration on the preceding 0.8.0 release, solidifying its position as a performance-focused alternative to Underscore.js. Both versions offer developers a comprehensive suite of utility functions designed to streamline JavaScript development. These functions cover a wide range of tasks, including array manipulation, object handling, function binding, and more, enabling developers to write cleaner, more efficient code. The core value proposition remains consistent: providing a drop-in replacement for Underscore, promising enhanced performance, bug fixes, and an expanded feature set.
Looking at the provided data, the key distinction lies in the release dates. Version 0.8.1 was published on October 4th, 2012, a mere two days after version 0.8.0, released on October 2nd, 2012. This suggests that version 0.8.1 likely incorporates bug fixes or minor enhancements identified shortly after the initial 0.8.0 release. For developers, this emphasizes the project's commitment to rapid iteration and responsiveness to the community. While the descriptions are identical, the quick turnaround suggests a refinement process, potentially addressing edge cases or performance bottlenecks discovered immediately after the previous release. Therefore, opting for version 0.8.1 is generally advisable, as it likely incorporates immediate improvements to an already robust utility library. Both versions reinforce Lodash's appeal in providing well-documented, optimized functions for everyday JavaScript tasks.
All the vulnerabilities related to the version 0.8.1 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.
