Redis Software release notes 8.2.0-25 (July 2026)

Database-scoped management roles. Data path command auditing.

Redis Software

Redis Software version 8.2.0 is now available!

Highlights

This version offers:

Database-scoped management roles
Data path command auditing
FIPS 140-3 support

New in this release

Database-scoped management roles

You can now scope the db_member and db_viewer management roles to specific databases instead of granting access to every database in the cluster. This lets you give application or tenant teams management access to only their own databases in a shared cluster.

To scope a role, specify the databases it applies to using the new resources field when you create or update a role. For example, "resources": [{"type": "db", "uids": ["1", "2"]}] scopes the role to databases 1 and 2.
Roles without a resources scope continue to apply to all databases, so existing roles are unaffected.
Users assigned a database-scoped role see only their authorized databases in the Cluster Manager UI and REST API responses, including database lists, metrics, alerts, and event logs. Other databases are hidden.

Data path command auditing

Redis Software now supports auditing of data path commands (CRUD operations), in addition to the existing connection auditing. This lets you record which commands run against a database, along with the connection and authentication context, and stream the audit records to an external audit destination for security monitoring and compliance.

Enable auditing per database with the new audit_settings configuration, choosing to audit connection events only (connection) or both connection events and commands (connection_and_crud).
Filter audited commands by username, source IP address, or both to control the volume of audit data.
Monitor the auditing pipeline with new audit_sink_* metrics.

For more information, see Audit events.

FIPS 140-3 support

Redis supports deployments on RHEL 9 VMs using cryptographic libraries based on FIPS 140-3 validated modules, enabling the use of FIPS-approved cryptographic algorithms in supported environments.

Install Redis Software on a RHEL 9 host that has FIPS mode enabled. See Supported platforms for the platforms validated for FIPS mode.
In FIPS mode, Redis Software uses only FIPS-approved cryptographic algorithms and cipher suites; non-approved ciphers and algorithms are blocked.
Because FIPS mode fixes the allowed cipher suites, you cannot change the cluster's TLS cipher suites while FIPS mode is enabled. Requests to update them return a tls_cipher_update_not_allowed error.

For FIPS-mode limitations, see Increased memory usage in FIPS mode and SFTP storage not supported in FIPS mode.

Enhancements

Disable Basic authentication for the REST API. You can now disable Basic and Digest authentication for the cluster management REST API using the new control_plane_basic_authentication cluster setting. Basic authentication remains enabled by default; when you disable it, the cluster rejects Basic and Digest authentication on inbound REST API requests. Configure it with rladmin tune cluster or an update cluster settings REST API request. See Disable basic authentication for the REST API.
Expose database tags in metrics. You can now expose selected database tags as labels in v2 metrics through a new db_tags metric, so you can group, filter, and alert on database metrics by your own tags. Enable it in the cluster's metrics configuration using the expose_db_tags and metrics_tag_keys_exposed settings.
Faster replica synchronization. Redis Software now manages gradual (parallel) synchronization through a gradual_sync_policy that applies tuned defaults for common scenarios, such as migration, adding a replica, and Active-Active. This speeds up replica bootstrap in multi-node and multi-shard deployments, such as during upgrades and scaling events, while leaving small deployments unaffected. You can select a policy or set custom parameters with rladmin tune db or the REST API.
Certificate–cipher suite validation. When you upload a cluster certificate, Redis Software now validates that the certificate is compatible with the configured cipher suites and rejects incompatible certificates at upload time, so mismatches are caught early instead of surfacing later. For example, uploading an ECDSA certificate while only RSA-authenticated cipher suites are configured now fails at upload. The check applies to the control-plane certificates (such as api, cm, and metrics_exporter) and to the proxy certificate against the data-path cipher suites. If an upload is rejected, update either the certificate or the configured cipher suites so they are compatible.

Resolved issues

RS200909: Fixed an issue where alert emails were not sent when the SMTP server was configured with STARTTLS and username/password authentication.
RS199037: Fixed an issue where Active-Active (CRDB) shard creation could fail with an invalid CRDT key type error.
RS199021: Fixed an issue where LDAP authentication could fail when a user's mapped group appeared beyond roughly the 100th entry in the group query results.
RS199012: Fixed a memory leak in dmcproxy that could occur when a multi-key command received a local MOVED or CROSSSLOT response.
RS198858: Added a readiness endpoint to the envoy_control_plane service to improve health reporting.
RS197703: Fixed an issue where an exception during first-node bootstrap could leave a cluster partially created without its modules.
RS196975: Fixed an issue where deleting and updating a user at the same time could corrupt the user record stored on the cluster, which was the underlying cause of cluster-wide ACL authentication failures.
RS196954: Fixed an issue where a user configuration could become corrupted if it was deleted and updated concurrently, which broke ACL authentication for all databases on the cluster and prevented users from connecting.
RS196903: Fixed an issue where upgrading a module could leave the shard manager stuck unless replica shards were stopped first.
RS196225: Fixed an issue where LDAP filters that use an OR clause to match multiple attributes could fail to find a unique DN for some users after upgrading to Redis Software version 8.0.x.
RS195811: Fixed an issue where the search-workers-priority-bias-threshold configuration could not be set at runtime.
RS195106: Fixed a cluster upgrade issue where adding multiple nodes with a new version simultaneously to a cluster could cause node configuration data to be incorrectly deleted and lead to node addition failures.
RS195089: Fixed an issue where a major reconfiguration of an Active-Active database could cause an unnecessary full synchronization across all participating clusters.
RS194243: Fixed a memory leak in the Active-Active database syncer that could occur when a participating cluster became unavailable but was not removed from the CRDB configuration.
RS193861: Fixed an issue where a cluster could become unresponsive after a node was redeployed.
RS192993: Fixed an issue where creating a new user with just-in-time (JIT) provisioning could cause authentication to fail for all databases that use ACL-only authentication.
RS192582: Fixed an issue where the creation of Redis 8.x Active-Active databases could fail when no modules were specified due to missing module semantic versions in requests.
RS192405: Improved dmcproxy SSL handshake error messages to provide actionable context when a TLS version mismatch occurs.
RS192048: Fixed an issue where a feature set incompatibility could cause a database upgrade to fail.
RS191757: Fixed an issue where a replica shard could fail to replicate and block failover for an extended period.
RS191347: Fixed an issue where an orphaned shard on a node could block maintenance mode and leave a database in an active-change-pending state.
RS190875: Fixed an issue where ciphers that use SHA-1 could not be removed when FIPS mode was enabled. FIPS mode now excludes SHA and CHACHA20 from control_cipher_suites.
RS188659: Fixed an issue where a valid IPv6 address could be misidentified as the localhost loopback address.
RS181161: Fixed an issue where access control users in an error state could not be deleted.

RS148518: Fixed an issue where an SMTP server could not be configured to send email alerts.
RS144017: Fixed an issue where synchronization could fail with a -BUSYKEY Target key name already exists error.

Version changes

Breaking changes

Redis Software version 8.2.0 introduces the following breaking changes:

Local import from Redis Software system directories is no longer supported. To improve security, database imports that use the mount_point source can no longer read files from Redis Software system directories, including /opt/redislabs, /var/opt/redislabs, /etc/opt/redislabs, and any of their subdirectories.
- Import operations that reference files in these directories now fail.
- Store import files in a non-system location accessible to Redis Software before you start the import.
smtp_password is now a write-only field in the Cluster API. To improve security, the API no longer returns the SMTP password in responses to GET /v1/cluster, and the Cluster Manager UI no longer reads or displays the existing password.
- Applications or scripts that previously expected smtp_password to be returned by the Cluster API no longer receive this field.
- When you update SMTP settings, the existing password cannot be retrieved. To change the SMTP password, provide a new password as part of the update request.
Custom module upload is disabled by default. To improve security, custom (user-defined) module uploads are now disabled by default. A new cluster setting, allow_modules_upload, controls access to the custom module upload APIs. When this setting is disabled (the default), requests to POST /v2/modules/user-defined and POST /v2/local/modules/user-defined/artifacts return 403 modules_upload_disabled, regardless of user role.
- To enable custom module uploads, set allow_modules_upload to true with a PUT /v1/cluster request.
- Applications or automation that call the custom module upload APIs directly receive a 403 modules_upload_disabled response until the setting is enabled.
- Existing functionality for listing, deleting, and loading modules is unchanged.

OpenSSL version

Redis Software version 8.0.16 and later requires OpenSSL 3.3 or later.

Reserved ports

Make sure the following ports are open before upgrading Redis Software.

The following port was added as a reserved port in Redis Software version 8.0.18; however, it is optional instead of reserved in Redis Software version 8.0.20-44:

Port	Process name	Usage
3357	reconciliation_tree_grpc	Internal communication

Ports reserved as of Redis Software version 7.22.0:

Port	Process name	Usage
3346	cluster_api_internal	Cluster API internal port
3351	cluster_watchdog_grpc_api	Cluster watchdog now supports gRPC
3352	grpc_service_mesh	gRPC communication between nodes
3353	local_grpc_service_mesh	Local gRPC services
3354	grpc_gossip_envoy	gRPC gossip protocol communication between nodes
3355	authentication_service	Authentication service internal port

Ports reserved as of Redis Software version 7.8.2:

Port	Process name	Usage
3347	cert_exporter	Reports cluster certificate metrics
3348	process_exporter	Reports process metrics for DMC and Redis processes
3349	cluster_wd_exporter	Reports cluster watchdog metrics
3350	db_controller	Internode communication
9091	node_exporter	Reports host node metrics related to CPU, memory, disk, and more
9125	statsd_exporter	Reports push metrics related to the DMC and syncer, and some cluster and node metrics

See Ports and port ranges used by Redis Software for a complete list.

Deprecations

The db_conns_auditing cluster policy and database configuration field is deprecated. Use the audit_settings.audit_mode field instead. Setting db_conns_auditing to true is equivalent to setting audit_mode to connection. See Audit events for the current auditing configuration.
The gradual_src_mode, gradual_sync_mode, and gradual_sync_max_shards_per_source parameters are deprecated. Use gradual_sync_policy instead. You can set it with rladmin tune db or the REST API.
The old_password field in POST /v1/users/password and PUT /v1/users/password requests is deprecated and ignored. It was optional and had no effect when adding or resetting a password, so you can remove it from these requests. old_password is still required for DELETE /v1/users/password, which uses it to identify the password to delete.
The following REST API fields, deprecated since Redis Software version 6.4.2, are removed in this release:
- use_ipv6 (cluster object) — use use_external_ipv6 instead.
- redis_cleanup_job_settings (job scheduler object) — use persistence_cleanup_scan_interval instead.

Supported platforms

Known issues

RS155734: Endpoint availability metrics do not work as expected due to a calculation error.

Known limitations

Increased memory usage in FIPS mode

FIPS-enabled builds use more memory than non-FIPS builds. Each Go-based control-plane service uses roughly 34 MB more when running in FIPS mode, which adds up to approximately 210 MB of additional memory per node. Account for this overhead when sizing FIPS-enabled deployments. This limitation affects FIPS-enabled builds only.

SFTP storage not supported in FIPS mode

FIPS-enabled builds do not support SFTP as a storage location for backups, imports, or exports, because the SFTP library is not FIPS-compliant. In FIPS mode, use a different storage location. This limitation affects FIPS-enabled builds only.

Redis Search query failures during rolling upgrades across the 8.4 version boundary

Redis Search queries can fail during a rolling upgrade when a cluster contains shards running Redis versions earlier than 8.4 and shards running Redis version 8.4 or later, due to an internal protocol change introduced in version 8.4. This issue affects only clusters where parallel_shards_upgrade has been changed from its default value of 0. If both conditions apply, expect Redis Search downtime until all nodes are upgraded.

Trim ACKED not supported for Active-Active 8.4 databases

For Active-Active databases running Redis database version 8.4, the ACKED option is not supported for trimming commands.

Rolling upgrade limitation for clusters with custom or deprecated modules

Due to module handling changes introduced in Redis Software version 8.0, upgrading a cluster that contains custom or deprecated modules, such as RedisGraph and RedisGears v2, can become stuck when adding a new node to the cluster during a rolling upgrade.

Module commands limitation during Active-Active database upgrades to Redis 8.0

When upgrading an Active-Active database to Redis version 8.0, you cannot use module commands until all Active-Active database instances have been upgraded. Currently, these commands are not blocked automatically.

Redis 8.0 database cannot be created with flash

You cannot create a Redis 8.0 database with flash storage enabled. Create a Redis 8.0 database with RAM-only storage instead, or use Redis 8.2 for flash-enabled (Redis Flex) databases.

Cluster Manager UI limitations

The following legacy UI features are not yet available in the new Cluster Manager UI:

Purge an Active-Active instance.

Use crdb-cli crdb purge-instance instead.

Security

Redis Open Source security fixes compatibility

As part of Redis's commitment to security, Redis Software implements the latest security fixes available with Redis Open Source. Redis Software has already included the fixes for the relevant CVEs.

Some CVEs announced for Redis Open Source do not affect Redis Software due to different or additional functionality available in Redis Software that is not available in Redis Open Source.

Redis Software 8.2.0-25 supports Redis Open Source 8.6, 8.4, 8.2, 8.0, 7.4, 7.2, and 6.2. Below is the list of Redis Open Source CVEs and other security vulnerabilities fixed by version.
