Affected versions of this package are vulnerable to Prototype Pollution via the sdk function due to missing check if the attribute resolves to the object prototype.

To exploit vulnerability, someone may inject a malicious object from a user controllable input to aim function in aim.js. The input resolves to the object prototype thus modify the behavior of the program.

Poc:

var sdk = require("@aliconnect/sdk")
BAD_JSON = JSON.parse('{"__proto__":{"polluted":true}}');

Overview

Affected versions of this package are vulnerable to Prototype Pollution where the merge is invoked in M function unsafely Since the infected e argument with proto object missing check if it resolves to the object prototype, the malicious property are then copied on the Object prototype by the merge operation to the empty object and recursively affected all the objects in the program.

PoC

(async () => {
 const lib = await import('@bit/loader');

Overview

Affected versions of this package (<=5.1.62) are vulnerable to prototype pollution via mutIn and mutInManyUnsafe An attacker can manipulate the prototype of an object, potentially leading to the alteration of behavior of all objects inheriting from the affected prototype by passing specially crafted input to these functions.

In the PoC code below, paths.mutIn invoked with a polluted __proto__ property, this property passed as an argument from mutIn() in mut-in.js to defMutator() in mutator.js and then assigned to the destination as follows:

        return s ? (t = s[a]) ? (t[b] = x, s) : void 0 : void 0;

Overview

json-schema-ref-parser is an NPM package for Parse, Resolve, and Dereference JSON Schema $ref pointers.

Affected versions of this package are vulnerable to Prototype Pollution. An attacker can manipulate the prototype of an object, potentially leading to the alteration of behavior of all objects inheriting from the affected prototype by passing specially crafted input to this function.

Details:

The vulnerable functions: bundle(), parse(), resolve(), dereference() passes the argument options to an unsafe merge method, which recursively copy properties from one object to another. Such a function has the potential to modify any object reachable from the destination object, and the built-in Object.prototype is usually reachable through the special properties __proto__ and constructor.prototype.
