# Overview
|
|
|
|
|
|
|
|
|
|
This page contains the list of deprecations and important or breaking changes
|
|
|
|
|
for Vault 1.2.4 compared to 1.2.3. Please read it carefully.

## Detached Leases From Tokens in non-root Namespaces
|
|
|
|
|
|
|
|
|
|
In a non-root namespace, revocation of a token scoped to a non-root namespace
|
|
|
|
|
did not trigger the expected revocation of dynamic secret leases associated with
|
|
|
|
|
that token. As a result, dynamic secret leases in non-root namespaces may
|
|
|
|
|
outlive the token that created them. This vulnerability, CVE-2019-18616, affects
|
|
|
|
|
Vault Enterprise 0.11.0 and newer.
|
|
|
|
|
|
|
|
|
|
## Mount Filtering in Disaster Recovery Secondary Clusters
|
|
|
|
|
|
|
|
|
|
Disaster Recovery secondary clusters did not delete already-replicated data
|
|
|
|
|
after a mount filter has been created on an upstream Performance secondary
|
|
|
|
|
cluster. As a result, encrypted secrets may remain replicated on a Disaster
|
|
|
|
|
Recovery secondary cluster after application of a mount filter excluding those
|
|
|
|
|
secrets from replication. This vulnerability, CVE-2019-18617, affects Vault
|
|
|
|
|
Enterprise 0.8 and newer.
|
|
|
|
|
|
|
|
|
|
## Golang crypto/dsa CVE
|
|
|
|
|
|
|
|
|
|
Update version of Go to 1.12.12 to fix Go bug golang.org/issue/34960 which
|
|
|
|
|
corresponds to CVE-2019-17596.
|
|
|
|
|
|
|
|
|
|
## AWS Region Detection in Agent and CLI
|
|
|
|
|
|
|
|
|
|
If a custom sts_endpoint is configured, Vault Agent and the CLI should provide
|
|
|
|
|
the corresponding region via the region parameter (which already existed as a
|
|
|
|
|
CLI parameter, and has now been added to Agent). The automatic region detection
|
|
|
|
|
added to the CLI and Agent in 1.2 has been removed.
