Security Advisories 🚨

🚨 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.

🚨 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

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 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.

Recommendation

Update to version 4.17.12 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.

Recommendation

Update to version 4.17.11 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.

Recommendation

Update to version 4.17.5 or later.

👉 No CI detected

You don't seem to have any Continuous Integration service set up!

Without a service that will test the Depfu branches and pull requests, we can't inform you if incoming updates actually work with your app. We think that this degrades the service we're trying to provide down to a point where it is more or less meaningless.

This is fine if you just want to give Depfu a quick try. If you want to really let Depfu help you keep your app up-to-date, we recommend setting up a CI system:

* [Circle CI](https://circleci.com), [Semaphore ](https://semaphoreci.com) and [Github Actions](https://docs.github.com/actions) are all excellent options. * If you use something like Jenkins, make sure that you're using the Github integration correctly so that it reports status data back to Github. * If you have already set up a CI for this repository, you might need to check your configuration. Make sure it will run on all new branches. If you don’t want it to run on every branch, you can whitelist branches starting with `depfu/`.
