Description Pedro Sampaio 2023-04-25 13:33:24 UTC

"Vault and Vault Enterprise 1.8.0 through 1.8.8, and 1.9.3 allowed the PKI secrets engine under certain configurations to issue wildcard certificates to authorized users for a specified domain, even if the PKI role policy attribute allow_subdomains is set to false. Fixed in Vault Enterprise 1.8.9 and 1.9.4.
