Description
hpke-js is a Hybrid Public Key Encryption (HPKE) module built on top of Web Cryptography API. Prior to version 1.7.5, the public SenderContext Seal() API has a race condition which allows for the same AEAD nonce to be re-used for multiple Seal() calls. This can lead to complete loss of Confidentiality and Integrity of the produced messages. This issue has been patched in version 1.7.5.

Executive Summary

The vulnerability in hpke-js prior to version 1.7.5 is a race condition in the public SenderContext Seal() API that causes the same AEAD nonce to be reused for multiple Seal() calls. This nonce reuse can lead to a complete loss of confidentiality and integrity of the encrypted messages.

Impact Analysis

This vulnerability can lead to a complete loss of confidentiality and integrity of messages encrypted using the affected hpke-js module. An attacker could exploit the nonce reuse to decrypt or tamper with messages, compromising sensitive data and communications.

Mitigation Strategies

Upgrade hpke-js to version 1.7.5 or later, as this version contains the patch that fixes the race condition causing nonce reuse. Avoid using vulnerable versions prior to 1.7.5 to prevent loss of confidentiality and integrity.
