How to Fix CVE-2023-45827

To remediate this vulnerability, upgrade all affected @clickbar/dot diver dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@clickbar/dot-diver fixed: 1.0.2 
npm install @clickbar/dot-diver@1.0.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls @clickbar/dot-diver

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2023-45827, inspect your project dependencies using npm:

npm ls @clickbar/dot-diver

Analyze the terminal output to locate any version of @clickbar/dot diver in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.2), your application is affected.

Note: The npm ls @clickbar/dot-diver command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution'), where the product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype. In @clickbar/dot diver, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary There is a Prototype Pollution(PP) vulnerability in dot-diver. It can leads to RCE. ### Details ```javascript //https://github.com/clickbar/dot-diver/tree/main/src/index.ts:277 // eslint-disable-next-line @typescript-eslint/no-unsafe-member-access objectToSet[lastKey] = value ``` In this code, there is no validation for Prototpye Pollution. ### PoC ```javascript import { getByPath, setByPath } from '@clickbar/dot-diver' console.log({}.polluted); // undefined setByPath({},'constructor.prototype.polluted', 'foo'); console.log({}.polluted); // foo ``` ### Impact It is Prototype Pollution(PP) and it can leads to Dos, RCE, etc. ### Credits Team : NodeBoB 최지혁 ( Jihyeok Choi ) 이동하 ( Lee Dong Ha of ZeroPointer Lab ) 강성현    ( kang seonghyeun ) 박성진    ( sungjin park ) 김찬호    ( Chanho Kim ) 이수영    ( Lee Su Young ) 김민욱    ( MinUk Kim )
