HashiCorp Vault Enterprise’s Sentinel EGP policy feature incorrectly allowed requests to be processed in parent and sibling namespaces. Fixed in 1.5.6 and 1.6.1.
HashiCorp Vault and Vault Enterprise versions 1.0 and newer allowed leases created with a batch token to outlive their TTL because expiration time was not scheduled correctly. Fixed in 1.4.7 and 1.5.4.
