Vault and Vault Enterprise (“Vault”) TLS certificate auth method did not correctly validate client certificates when configured with a non-CA certificate as trusted certificate. In this configuration, an attacker may be able to craft a malicious certificate that could be used to bypass authentication. Fixed in Vault 1.15.5 and 1.14.10.
Vault and Vault Enterprise (“Vault”) may expose sensitive information when enabling an audit device which specifies the `log_raw` option, which may log sensitive information to other audit devices, regardless of whether they are configured to use `log_raw`.
HashiCorp Vault and Vault Enterprise 1.12.0 and newer are vulnerable to a denial of service through memory exhaustion of the host when handling large unauthenticated and authenticated HTTP requests from a client. Vault will attempt to map the request to memory, resulting in the exhaustion of available memory on the host, which may cause Vault to crash.
Fixed in Vault 1.15.4, 1.14.8, 1.13.12.
