##### 2.0.4
###### August 04, 2026

BREAKING CHANGES:

* containers: The following packages have been removed from UBI based container
images: gnupg, openssl, procps.

SECURITY:

* acl: Fix privilege-escalation vulnerability where a `denied_parameters` constraint on the `policies` request field could be bypassed by submitting a mixed-case policy name (e.g. "Super-Admin" instead of "super-admin"). Vault now normalizes the `policies` parameter to lowercase before evaluating `allowed_parameters`/`denied_parameters` constraints.
* identity/scim (enterprise): The `identity/entity/merge` endpoint now rejects requests that involve any SCIM-managed entity, preventing privileged operators from bypassing SCIM ownership guardrails to transfer aliases, group memberships, or policies across SCIM boundaries.
* identity: Prevent the entity batch-delete endpoint (identity/entity/batch-delete) from deleting the underlying storage of entities that belong to another namespace.
* identity: entity/name updates now reject mismatched id or external_id selectors to prevent retargeting updates to a different entity

CHANGES:

* auth/oci: Update plugin to [v0.21.3](https://github.com/hashicorp/vault-plugin-auth-oci/releases/tag/v0.21.3)
* core: Bump Go version to 1.26.5.
* core: remove support for duplicate attributes in HCL configuration files and policy definitions. Parsing HCL with
duplicate attributes now always fails, and the VAULT_ALLOW_PENDING_REMOVAL_DUPLICATE_HCL_ATTRIBUTES environment
variable that previously restored the legacy behavior has been removed.

FEATURES:

* secrets: Added ability to view secrets in YAML format

IMPROVEMENTS:

* auth/cert: Support login via x-forwarded cert headers even with tls disabled on the vault listener.
* core (enterprise): Add an endpoint at `sys/config/oauth-resource-server/id/:config_id` to read oauth resource server profiles by `config_id`
* core (enterprise): Make OAuth resource server JWT `typ` validation more permissive for tokens from IdPs such as Okta by allowing a missing `typ` header, while restricting present `typ` values to `at+jwt`, `application/at+jwt`, and `JWT`.
* core (entreprise): Ameriolate sealwrap lock contention for core paths.
* core/acl: Adds a global `deny_slash_in_templated_path` configuration option to reject the presence of slashes in rendered identity templates in policies, defaulting to `false`.
* core/identity: Adds a global `deny_slash_in_templated_path` configuration option to reject the presence of slashes in rendered identity templates in policies, defaulting to `false`.
* core/managed-keys/PKCS#11 (enterprise): Providing a non-empty value for one field while the other is already saved is rejected. To switch addressing modes, you must explicitly clear the old field by sending it as an empty string ("") in the same request alongside the new value.
* core/managed-keys/PKCS#11 (enterprise): slot and token_label are now strictly enforced as mutually exclusive identifiers for an HSM token
* events: Add `VAULT_EVENT_NOTIFICATIONS_BOUNDED_QUEUE_SIZE` environment variable to configure bounded event queues for event notification subscribers. Set to a positive integer (e.g., 16) to enable buffered channels of that size (maximum 1000). This prevents resource exhaustion in deployments with high subscriber counts, but comes at the cost of the potential for subscribers to miss events. Defaults to 0 (unbuffered) for backward compatibility.
* identity/scim (enterprise): Added filtering support to the `GET /scim/v2/Users` and `GET /scim/v2/Groups` endpoints per RFC 7644. Supported filters: `userName eq`, `externalId eq`, `active eq`, and `meta.lastModified gt/ge/lt/le` for Users; `displayName eq` and `meta.lastModified gt/ge/lt/le` for Groups. Unsupported filter expressions return HTTP 400. `ServiceProviderConfig` now advertises `filter.supported: true`.
* identity/scim (enterprise): Improve SCIM User and Group listing endpoint performance by using pr

SECURITY:

* auth/radius: Added case_insensitive_names toggle to prevent username collisions and enable case-insensitive user handling.
* core/acl: Fix LIST ACL bypass where a trailing-slash request could skip a more-specific deny rule.
* core: Use constant-time recovery token comparison

CHANGES:

* auth/cf: Update plugin to [v0.23.1](https://github.com/hashicorp/vault-plugin-auth-cf/releases/tag/v0.23.1)
* core/acl: LIST requests with a trailing slash now correctly respect more-specific deny policies. Previously, a deny on `path "kv/*" { deny }` could be bypassed for `LIST kv/private/` if a broader allow `path "kv/*"` also existed. Policies relying on the previous (incorrect) behavior may now be denied.
* core: Vault will now redirect non-canonicalized paths (containing `/./`, `/../`, or `//`) to a cleaned path, instead of rejecting these requests
* secrets/azure: Update plugin to [v0.26.5+ent](https://github.com/hashicorp/vault-plugin-secrets-azure/releases/tag/v0.26.5+ent)

FEATURES:

* **AI Agent Support (Beta/Enterprise)**: Adds beta support for first-class AI agents. Adds
an Agent Registry to register agents, and adds support for using Vault as an OAuth resource server
for registered agent entities. When configured, allows OAuth 2.0 JWTs to be used to directly authorize
requests to Vault, without needing a Vault token.

IMPROVEMENTS:

* consumption-billing: Add a new `sys/billing/config` endpoint to allow configuration of billing data retention (min 13 months, max 6 years).
* core (Enterprise): Make deadlock detection in sealwrap configurable by adding "sealwrap" to existing configuration detect_deadlocks.
* identity/scim (enterprise): Update PATCH operations on scim/v2/Users to allow multiple modifications in the same patch call, support for patch operations on user metadata and name in addition to active status, and allow specifying `path` value in patch operations
* sdk/helper/keysutil: The lock manager's GetPolicy function now always returns a locked Policy, even when caching is
enabled. The PolicyRequest struct has a new field to indicate whether the caller requires a write lock on the policy.
* ui (enterprise): Migrate charts from Lineal to Carbon Charts in the Client usage overview and Vault usage dashboard.

BUG FIXES:

* core/rotationMgr: Fix storage routing for local mounts in namespaces to prevent metadata replication and ensure GDPR compliance.
* kmip (enterprise): Fix a bug that prevents the legacy CA from working on a named listener.
* secret-sync (enterprise): Fix GCP Secret Manager replication policy persistence across Vault restarts.

##### 1.21.2
###### January 07, 2026

CHANGES:

* auth/oci: bump plugin to v0.20.1
* core: Bump Go version to 1.25.5
* packaging: Container images are now exported using a compressed OCI image layout.
* packaging: UBI container images are now built on the UBI 10 minimal image.
* secrets/azure: Update plugin to v0.25.1+ent. Improves retry handling during Azure application and service principal creation to reduce transient failures.
* storage: Upgrade aerospike client library to v8.

IMPROVEMENTS:

* core: check rotation manager queue every 5 seconds instead of 10 seconds to improve responsiveness
* go: update to golang/x/crypto to v0.45.0 to resolve GHSA-f6x5-jh6r-wrfv, GHSA-j5w8-q4qc-rx2x, GO-2025-4134 and GO-2025-4135.
* rotation: Ensure rotations for shared paths only execute on the Primary cluster's active node. Ensure rotations for local paths execute on the cluster-local active node.
* sdk/rotation: Prevent rotation attempts on read-only storage.
* secrets-sync (enterprise): Added support for a boolean force_delete flag (default: false). When set to true, this flag allows deletion of a destination even if its associations cannot be unsynced. This option should be used only as a last-resort deletion mechanism, as any secrets already synced to the external provider will remain orphaned and require manual cleanup.
* secrets/pki: Avoid loading issuer information multiple times per leaf certificate signing.

BUG FIXES:

* core/activitylog (enterprise): Resolve a stability issue where Vault Enterprise could encounter a panic during month-end billing activity rollover.
* http: skip JSON limit parsing on cluster listener.
* quotas: Vault now protects plugins with ResolveRole operations from panicking on quota creation.
* replication (enterprise): fix rare panic due to race when enabling a secondary with Consul storage.
* rotation: Fix a bug where a performance secondary would panic if a write was made to a local mount.
* secret-sync (enterprise): Improved unsync error handling by treating cases where the destination no longer exists as successful.
* secrets-sync (enterprise): Corrected a bug where the deletion of the latest KV-V2 secret version caused the associated external secret to be deleted entirely. The sync job now implements a version fallback mechanism to find and sync the highest available active version, ensuring continuity and preventing the unintended deletion of the external secret resource.
* secrets-sync (enterprise): Fix issue where secrets were not properly un-synced after destination config changes.
* secrets-sync (enterprise): Fix issue where sync store deletion could be attempted when sync is disabled.
* ui/pki: Fix handling of values that contain commas in list fields like `crl_distribution_points`.
