vault: Vault Enterprise Does Not Verify Existing Voter Status When Joining An Integrated Storage HA Node
HashiCorp Vault Enterprise 1.7.0 through 1.9.7, 1.10.4, and 1.11.0 clusters using Integrated Storage expose an unauthenticated API endpoint that could be abused to override the voter status of a node within a Vault HA cluster, introducing potential for future data loss or catastrophic failure. Fixed in Vault Enterprise 1.9.8, 1.10.5, and 1.11.1.
