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. 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.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
