GHSA-g233-2p4r-3q7v Hashicorp Vault vulnerable to denial of service through memory exhaustion

• Go github.com/hashicorp/vault: >= 1.2.0, < 1.18.1 → fixed in 1.18.1 • Go github.com/openbao/openbao: < 2.0.3 → fixed in 2.0.3

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.
