Description
OpenBao from 2.5.0 before 2.6.2 fails to enforce the PKI role allowed_ip_sans_cidr restriction on IP SANs taken from a CSR when use_csr_sans is enabled. Authenticated callers with sign permission can submit a CSR with an out-of-range IP SAN to pki/sign/<role> and obtain CA-signed certificates for unauthorized IPs.
