Attack profile from CVSS 4.0 · CNA. Fix status from CNA. Impact type from CWE-863.

Summary

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. An authenticated caller with sign permission can submit a CSR with an out-of-range IP SAN and obtain CA-signed certificates for unauthorized IP addresses. The flaw is an incorrect authorization check (CWE-863).
