How to Fix CVE-2023-26488

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

@openzeppelin/contracts fixed: 4.8.2 
npm install @openzeppelin/contracts@4.8.2
@openzeppelin/contracts-upgradeable fixed: 4.8.2 
npm install @openzeppelin/contracts-upgradeable@4.8.2
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 @openzeppelin/contracts

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2023-26488, inspect your project dependencies using npm:

npm ls @openzeppelin/contracts

Analyze the terminal output to locate any version of @openzeppelin/contracts in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.8.2), your application is affected.

Note: The npm ls @openzeppelin/contracts 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-682: Incorrect Calculation, where the product performs a calculation that generates incorrect or unintended results that are later used in security-critical decisions or resource management. In @openzeppelin/contracts, 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

### Impact The ERC721Consecutive contract designed for minting NFTs in batches does not update balances when a batch has size 1 and consists of a single token. Subsequent transfers from the receiver of that token may overflow the balance as reported by `balanceOf`. The issue exclusively presents with batches of size 1. ### Patches The issue has been patched in 4.8.2. <!-- ### References -->
