# Overview
|
|
|
|
This page contains the list of deprecations and important or breaking changes
|
|
for Vault 1.12.x compared to 1.11. Please read it carefully.
|
|
|
|
## Changes
|
|
|
|
### Supported Storage Backends
|
|
|
|
Vault Enterprise will now perform a supported storage check at startup. There is no impact on open-source Vault users.
|
|
|
|
@include 'ent-supported-storage.mdx'
|
|
|
|
@include 'consul-dataplane-upgrade-note.mdx'
|
|
|
|
### External Plugin Loading
|
|
|
|
Vault 1.12.0 introduced a change to how external plugins are loaded. Prior to
|
|
Vault 1.12.0 plugins were lazy loaded on startup. This means that plugin
|
|
processes were killed after a successful mount and then respawned when a
|
|
request is routed to them. Vault 1.12.0 introduced auto mutual TLS for
|
|
secrets/auth plugins so we do not lazy load them on startup anymore.
|
|
|
|
## Known Issues
|
|
|
|
### Pinning to builtin plugin versions may cause failure on upgrade
|
|
|
|
1.12.0 introduced plugin versions, and with it, the ability to explicitly specify
|
|
the builtin version of a plugin when mounting an auth, database or secrets plugin.
|
|
For example, `vault auth enable -plugin-version=v1.12.0+builtin.vault approle`. If
|
|
there are any mounts where the _builtin_ version was explicitly specified in this way,
|
|
Vault may fail to start on upgrading to 1.12.1 due to the specified version no
|
|
longer being available.
|
|
|
|
To check whether a mount path is affected, read the tune information, or the
|
|
database config. The affected plugins are `snowflake-database-plugin@v0.6.0+builtin`
|
|
and any plugins with `+builtin.vault` metadata in their version.
|
|
|
|
In this example, the first two mounts are affected because `plugin_version` is
|
|
explicitly set and is one of the affected versions. The third mount is not
|
|
affected because it only has `+builtin` metadata, and is not the Snowflake
|
|
database plugin. All mounts where the version is omitted, or the plugin is
|
|
external (regardless of whether the version is specified) are unaffected.
|
|
|
|
-> **NOTE:** Make sure you use Vault CLI 1.12.0 or later to check mounts.
|
|
|
|
```shell-session
|
|
$ vault read sys/auth/approle/tune
|
|
Key Value
|
|
--- -----
|
|
...
|
|
plugin_version v1.12.0+builtin.vault
|
|
|
|
$ vault read database/config/snowflake
|
|
Key Value
|
|
--- -----
|
|
...
|
|
plugin_name snowflake-database-plugin
|
|
plugin_version v0.6.0+builtin
|
|
|
|
$ vault read sys/auth/kubernetes/tune
|
|
Key Value
|
|
--- -----
|
|
...
|
|
plugin_version v0.14.0+builtin
|
|
```
|
|
|
|
As it is not currently possible to unset the plugin version, there are 3 possible
|
|
remediations if you have any affected mounts:
|
|
|
|
* Upgrade Vault directly to 1.12.2 once released
|
|
* Upgrade to an external version of the plugin before upgrading to 1.12.1;
|
|
* Using the [tune API](/vault/api-docs/system/auth#tune-auth-method) for auth methods
|
|
* Using the [tune API](/vault/api-docs/system/mounts#tune-mount-configuration) for secrets plugins
|
|
* Or using the [configure connection](/vault/api-docs/secret/databases#configure-connection)
|
|
API for database plugins
|
|
* Unmount and remount the path without a version specified before upgrading to 1.12.1.
|
|
**Note:** This will delete all data and leases associated with the mount.

The bug was introduced by commit
|
|
https://github.com/hashicorp/vault/commit/c36330f4c713b886a8a23c08cbbd862a7c530fc8.
|
|
|
|
#### Impacted Versions
|
|
|
|
Affects upgrading from 1.12.0 to 1.12.1. All other upgrade paths are unaffected.
|
|
1.12.2 will introduce a fix that enables upgrades from affected deployments of
|
|
1.12.0.
|
|
|
|
### Mounts associated with deprecated builtin plugins will result in core shutdown on upgrade
|
|
|
|
As of 1.12.0 Standalone (logical) DB Engines and the AppId Auth Method have been
|
|
marked with the `Pending Removal` status. Any attempt to unseal Vault with
|
|
mounts backed by one of these builtin plugins will result in an immediate
|
|
shutdown of the Vault core.
|
|
|
|
-> **NOTE** In the event that an external plugin with the same name and type as
|
|
a deprecated builtin is deregistered, any subsequent unseal of Vault will also
|
|
result in a core shutdown.
|
|
|
|
```shell-session
|
|
$ vault plugin register -sha256=c805cf3b69f704dfcd5176ef1c7599f88adbfd7374e9c76da7f24a32a97abfe1 auth app-id
|
|
Success! Registered plugin: app-id
|
|
$ vault auth enable -plugin-name=app-id plugin
|
|
Success! Enabled app-id auth method at: app-id/
|
|
$ vault auth list -detailed
|
|
app-id/ app-id auth_app-id_3a8f2e24 system system default-service replicated false false map[] n/a 0018263c-0d64-7a70-fd5c-50e05c5f5dc3 n/a n/a c805cf3b69f704dfcd5176ef1c7599f88adbfd7374e9c76da7f24a32a97abfe1 n/a
|
|
$ vault plugin deregister auth app-id
|
|
Success! Deregistered plugin (if it was registered): app-id
|
|
$ vault plugin list -detailed | grep "app-id"
|
|
app-id auth v1.12.0+builtin.vault pending removal
|
|
```
|
|
|
|
The remediation for affected mounts is to set the
|
|
[VAULT_ALLOW_PENDING_REMOVAL_MOUNTS](/vault/docs/commands/server#vault_allow_pending_removal_mounts)
|
|
environment variable and replace any `Pending Removal` feature with the
|
|
[preferred alternative
|
|
feature](/vault/docs/deprecation/faq#q-what-should-i-do-if-i-use-mount-filters-appid-or-any-of-the-standalone-db-engines).
|
|
|
|
For more information on the phases of deprecation, see the [Deprecation Notices
|
|
FAQ](/vault/docs/deprecation/faq#q-what-are-the-phases-of-deprecation).
|
|
|
|
#### Impacted Versions
|
|
|
|
Affects upgrading from any version of Vault to 1.12.x. All other upgrade paths
|
|
are unaffected.
|
|
|
|
### `vault plugin list` fails when audit logging is enabled
|
|
|
|
If audit logging is enabled, Vault will fail to audit the response from any
|
|
calls to the [`GET /v1/sys/plugins/catalog`](/vault/api-docs/system/plugins-catalog#list-plugins)
|
|
endpoint, which causes the whole request to fail and return a 500 internal
|
|
server error. From the CLI, this looks like the following:
|
|
|
|
```shell-session
|
|
$ vault plugin list
|
|
Error listing available plugins: data from server response is empty
|
|
```
|
|
|
|
It will produce errors in Vault Server's logs such as:
|
|
|
|
```text
|
|
2022-11-30T20:04:22.397Z [ERROR] audit: panic during logging: request_path=sys/plugins/catalog error="reflect: reflect.Value.Set using value obtained using unexported field"
|
|
2022-11-30T20:04:22.398Z [ERROR] core: failed to audit response: request_path=sys/plugins/catalog
|
|
error=
|
|
| 1 error occurred:
|
|
| * panic generating audit log
|
|
|
|
|
```
|
|
|
|
As a workaround, [listing plugins by type](/vault/api-docs/system/plugins-catalog#list-plugins-1)
|
|
will succeed:
|
|
|
|
* `vault list sys/plugins/catalog/auth`
|
|
* `vault list sys/plugins/catalog/database`
|
|
* `vault list sys/plugins/catalog/secret`
|
|
|
|
The bug was introduced by commit
|
|
https://github.com/hashicorp/vault/commit/76165052e54f884ed0aa2caa496083dc84ad1c19.
|
|
|
|
#### Impacted Versions
|
|
|
|
Affects versions 1.12.0, 1.12.1, and 1.12.2. A fix will be released in 1.12.3.
|
|
|
|
### PKI OCSP GET requests return malformed request responses
|
|
|
|
If an OCSP GET request contains a '+' character, a malformed request response will be
|
|
returned instead of properly processing the request due to a double decoding issue within the
|
|
handler.
|
|
|
|
As a workaround, OCSP POST requests can be used which are unaffected.
|
|
|
|
#### Impacted Versions
|
|
|
|
Affects version 1.12.3. A fix will be released in 1.12.4.
