Vault Enterprise will now perform a supported storage check at startup. There is no impact on open-source Vault users.

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.
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.

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 for auth methods
- Using the tune API for secrets plugins
- Or using the 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.
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.
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.
$ 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
environment variable and replace any Pending Removal
feature with the
preferred alternative
feature.

Affects upgrading from any version of Vault to 1.12.x. All other upgrade paths are unaffected.
If audit logging is enabled, Vault will fail to audit the response from any
calls to the GET /v1/sys/plugins/catalog
endpoint, which causes the whole request to fail and return a 500 internal
server error. From the CLI, this looks like the following:
$ vault plugin list
Error listing available plugins: data from server response is empty
It will produce errors in Vault Server's logs such as:
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 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.
Affects versions 1.12.0, 1.12.1, and 1.12.2. A fix will be released in 1.12.3.
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.
Affects version 1.12.3. A fix will be released in 1.12.4.
