OpenBao 2.2.0 before 2.6.4 and 2.7.0 before 2.7.1 contains an information disclosure vulnerability that exposes the tls_acme_eab_mac_key value through the sys/config/state/sanitized endpoint. Callers of the sanitized configuration endpoint can retrieve the ACME External Account Binding MAC key used for TLS listener certificates, letting them bind to the operator's ACME account.
