Official description
vault-secrets-webhook is a Kubernetes mutating webhook that makes direct secret injection into Pods possible. Prior to 1.23.1, parseVaultConfig() in pkg/webhook/config.go accepts the vault.security.banzaicloud.io/vault-addr annotation, MutateConfigMap and MutateSecret call newVaultClient in pkg/webhook/webhook.go, and vault.security.banzaicloud.io/vault-serviceaccount can cause a ServiceAccount JWT to be sent to an attacker-controlled Vault address. This issue is fixed in version 1.23.1.
