Redux version 0.5.1 is a minor patch release following closely on the heels of version 0.5.0. Both versions define themselves as an experiment in fully hot-reloadable Flux, indicating a focus on developer experience and ease of use, particularly within React-based applications. Examining the package.json data, the code dependencies for both versions remain identical, with packages like babel-runtime, invariant, lodash, and react pinned to the same version ranges. This suggests that the core functionality and external API compatibility are consistent between the two versions.
The development dependencies are also unchanged, indicating that the build process, linting rules, and testing environment have not been altered in this patch. This is a positive sign for developers, implying that upgrading from 0.5.0 to 0.5.1 should be straightforward without introducing any breaking changes in the development workflow. Given the minimal changes, the update from 0.5.0 to 0.5.1 likely addresses internal bug fixes, performance tweaks, or minor documentation improvements rather than introducing new features. The quick release of 0.5.1 after 0.5.0 suggests a critical, but small, issue was addressed rapidly. For developers already using Redux 0.5.0, upgrading to 0.5.1 is advisable to benefit from these potential improvements and ensure they are running the most stable build. The release date difference of less than an hour further reinforces the notion of a quick fix.
All the vulnerabilities related to the version 0.5.1 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.
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.
Cross-Site Scripting in react
Versions of react prior to 0.14.0 are vulnerable to Cross-Site Scripting (XSS). The package's createElement function fails to properly validate its input object, allowing attackers to execute arbitrary JavaScript in a victim's browser.
Upgrade to version 0.14.0 or later.
