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.
The product does not validate, or incorrectly validates, a certificate.
