CVE-2021-43998: Incorrect Permission Assignment for Critical Resource

December 2, 2021

HashiCorp Vault and Vault Enterprise 0.11.0 up to 1.7.5 and 1.8.4 templated ACL policies would always match the first-created entity alias if multiple entity aliases exist for a specified entity and mount combination, potentially resulting in incorrect policy enforcement. Fixed in Vault and Vault Enterprise 1.7.6, 1.8.5, and 1.9.0.
