## Overview

Vault Community and Vault Enterprise (“Vault”) clusters using Vault’s Integrated Storage backend are vulnerable to a denial-of-service (DoS) attack through memory exhaustion through a Raft cluster join API endpoint. An attacker may send a large volume of requests to the endpoint which may cause Vault to consume excessive system memory resources, potentially leading to a crash of the underlying system and the Vault process itself.

This vulnerability, CVE-2024-8185, is fixed in Vault Community 1.18.1 and Vault Enterprise 1.18.1, 1.17.8, and 1.16.12.

## Affected packages

- `github.com/hashicorp/vault >= 1.2.0, < 1.18.1`
- `github.com/openbao/openbao < 2.0.3`

## Remediation

Upgrade to a patched release:

- `github.com/hashicorp/vault 1.18.1`
- `github.com/openbao/openbao 2.0.3`
