CVE-2022-23541 Explained : Impact and Mitigation

A security vulnerability identified as CVE-2022-23541 has been discovered in the 'jsonwebtoken' library, specifically affecting versions

<= 8.5.1

. This vulnerability could result in the generation of forgeable public/private tokens from RSA to HMAC due to an insecure implementation of the key retrieval function.

Understanding CVE-2022-23541

This section provides insights into the nature and impact of the CVE-2022-23541 vulnerability.

What is CVE-2022-23541?

The 'jsonwebtoken' library, version

<= 8.5.1

, has been found to be vulnerable to an incorrect verification of tokens. By misconfiguring the key retrieval function referencing the

secretOrPublicKey

argument, attackers could potentially use a different algorithm and key combination in verification, leading to successful validation of forged tokens.

The Impact of CVE-2022-23541

The impact of this vulnerability is significant as it allows threat actors to create forgeable public/private tokens, compromising the integrity of the token verification process.

Technical Details of CVE-2022-23541

In this section, we delve into the technical aspects of the CVE-2022-23541 vulnerability.

Vulnerability Description

The issue arises from versions

<= 8.5.1

of the 'jsonwebtoken' library, where an insecure key retrieval function can result in incorrect token verification, enabling the validation of forged tokens.

Affected Systems and Versions
