October 12, 2021 (updated October 20, 2021)

HashiCorp Vault and Vault Enterprise 1.8.x through 1.8.4 may have an unexpected interaction between glob-related policies and the Google Cloud secrets engine. Users may, in some situations, have more privileges than intended, e.g., a user with read permission for the /gcp/roleset/* path may be able to issue Google Cloud service account credentials.
