Description Guilherme de Almeida Suckevicz 2021-12-01 17:04:17 UTC
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.
