Known issues

- RS131972: Creating an ACL that contains a line break in the Cluster Manager UI can cause shard migration to fail due to ACL errors.

Known limitations

#### Upload modules before OS upgrade

If the cluster contains any databases that use modules, you must upload module packages for the target OS version to a node in the existing cluster before you upgrade the cluster's operating system.

See [Upgrade a cluster's operating system]() for detailed upgrade instructions.

#### New 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.

- Search and export the log.

#### RedisGraph prevents upgrade to RHEL 9

You cannot upgrade from a prior RHEL version to RHEL 9 if the Redis Software cluster contains a RedisGraph module, even if unused by any database. The [RedisGraph module has reached End-of-Life](https://redis.com/blog/redisgraph-eol/) and is completely unavailable in RHEL 9.

#### Query results might include hash keys with lazily expired fields

If one or more fields of a hash key expire after an `FT.SEARCH` or `FT.AGGREGATE` query begins, Redis does not account for these lazily expired fields. As a result, keys with expired fields might still be included in the query results, leading to potentially incorrect or inconsistent results.

Security

#### Open source Redis security fixes compatibility

As part of Redis's commitment to security, Redis Software implements the latest [security fixes](https://github.com/redis/redis/releases) available with [open source Redis](https://github.com/redis/redis). Redis Software has already included the fixes for the relevant CVEs.

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

Redis Software 7.8.6-119 supports open source Redis 7.4, 7.2, and 6.2. Below is the list of open source Redis CVEs fixed by version.

Redis 7.4.x:

- (CVE-2025-32023) An authenticated user can use a specially crafted string to trigger a stack/heap out-of-bounds write on HyperLogLog operations, which can lead to remote code execution.

- (CVE-2025-21605) An unauthenticated client can cause unlimited growth of output buffers until the server runs out of memory or is terminated, which can lead to denial-of-service.

Redis 7.2.x:

- (CVE-2025-32023) An authenticated user can use a specially crafted string to trigger a stack/heap out-of-bounds write on HyperLogLog operations, which can lead to remote code execution.

- (CVE-2024-31449) An authenticated user may use a specially crafted Lua script to trigger a stack buffer overflow in the bit library, which may potentially lead to remote code execution.

- (CVE-2024-31228) An authenticated user can trigger a denial-of-service by using specially crafted, long string match patterns on supported commands such as `KEYS`, `SCAN`, `PSUBSCRIBE`, `FUNCTION LIST`, `COMMAND LIST`, and ACL definitions. Matching of extremely long patterns may result in unbounded recursion, leading to stack overflow and process crashes.

- (CVE-2023-41056) In some cases, Redis may incorrectly handle resizing of memory buffers, which can result in incorrect accounting of buffer sizes and lead to heap overflow and potential remote code execution.

- (CVE-2023-41053) Redis does not correctly identify keys accessed by `SORT_RO` and, as a result, may grant users executing this command access to keys that are not explicitly authorized by the ACL configuration. (Redis 7.2.1)

Redis 7.0.x:

- (CVE-2024-31449) An authenticated user may use a specially crafted Lua script to trigger a stack buffer overflow in the bit library, which may potentially lead to remote code execution.

- (CVE-2022-35977) Integer overflow in the Redis `SETRANGE` and `SORT`/`SORT_RO` commands can drive Redis to OOM panic. (Redis 7.0.8)

- (CVE-2022-35951) Executing an `XAUTOCLAIM` command on a stream key in a specific state, with a specially crafted `COUNT` argument, may cause an integer overflow, a subsequent heap overflow, and potentially lead to remote code execution. The problem affects Redis versions 7.0.0 or newer. (Redis 7.0.5)

- (CVE-2022-31144) A specially crafted `XAUTOCLAIM` command on a stream key in a specific state may result in heap overflow and potentially remote code execution. The problem affects Redis versions 7.0.0 or newer. (Redis 7.0.4)

- (CVE-2022-24834) A specially crafted Lua script executing in Redis can trigger a heap overflow in the cjson and cmsgpack libraries, and result in heap corruption and potentially remote code execution. The problem exists in all versions of Redis with Lua scripting support, starting from 2.6, and affects only authenticated and authorized users. (Redis 7.0.12)

- (CVE-2022-24736) An attacker attempting to load a specially crafted Lua script can cause NULL pointer dereference which will result in a crash of the `redis-server` process. This issue affects all versions of Redis. (Redis 7.0.0)

- (CVE-2022-24735) By exploiting weaknesses in the Lua script execution environment, an attacker with access to Redis can inject Lua code that will execute with the (potentially higher) privileges of another Redis user. (Redis 7.0.0)

Redis Software release notes 7.8.6-13 (March 2025)

Summary: Configurable hashing algorithm for user passwords. Dry run option to validate REST API requests for users and roles.

Overview

[Redis Software version 7.8.6](https://redis.io/downloads/#software) is now available! This release includes API enhancements that warranted a new minor version instead of a maintenance release for version 7.8.4. However, you can upgrade from 7.8.2 or 7.8.4 to 7.8.6 without issue.

Highlights

This version offers:

- Configurable hashing algorithm for user passwords

- Dry run option to validate REST API requests for users and roles

New in this release

New features

- The hashing algorithm for user passwords is now configurable using [`rladmin`]() or the [REST API](). When you [change the hashing algorithm](), it rehashes the administrator password and passwords for all users, including default users.

    The hashing algorithm options are `SHA-256` or `PBKDF2`. The default hashing algorithm is `SHA-256`.

    To change the password hashing algorithm, use one of the following methods:

    - [`rladmin cluster change_password_hashing_algorithm`]():

        [code example]

    - [Change password hashing algorithm REST API request]():

        [code example]

Enhancements

- If you create or update users or roles using the [REST API](), you can use the `dry_run` query parameter to validate the request without actually applying the update.

    - [Create role]() example request:

        [code example]

    - [Update role]() example request:

        [code example]

    - [Create user]() example request:

        [code example]

    - [Update user]() example request:

        [code example]

Redis Software release notes 7.8.6-152 (August 2025)

Overview

This is a maintenance release for Redis Software version 7.8.6.

Highlights

This version offers:

- Bug fixes for Active-Active syncing, event log entries for configuration changes made by LDAP users, LDAP mapping visibility in the Cluster Manager UI, database max_connections setting, and memory leaks when using Active-Active databases in Kubernetes.

New in this release

Redis database versions

Redis Software version 7.8.6 includes three Redis database versions: 7.4.0, 7.2.4, and 6.2.13.

The [default Redis database version]() is 7.4.

Redis module feature sets

Resolved issues

- RS140077: Fixed a syncer issue where the number of keys did not match across the instances of Active-Active databases reconfigured with `only_configuration` after cluster recovery.

- RS155910: Fixed an issue where event logs incorrectly attributed configuration changes to `system` instead of the user who made the changes if they authenticated using LDAP.

- RS144065: Fixed an issue where LDAP mappings created using the REST API without the `bdbs_email_alerts` field were not visible in the Cluster Manager UI.

- RS144380: Fixed an issue where updating a database configuration in the Cluster Manager UI reset `max_connections` to 0, which allowed unlimited client connections.

- RS149040: Fixed a Gunicorn memory leak when using Active-Active databases in Kubernetes (REAADB).

- RS110383: Fixed LDAP socket file permissions to allow users in the `redislabs` group to run commands.

Version changes

Behavior changes

- The system now preserves user-defined `max_connections` for databases instead of resetting the values to unlimited (0) when the database configuration is updated using the Cluster Manager UI. If you previously set a database's `max_connections` to a value that doesn't align with your expected workload, review and adjust your configuration to prevent unintended client disconnections in case the threshold is too low.

Supported platforms

The following table provides a snapshot of supported platforms as of this Redis Software release. See the [supported platforms reference]() for more details about operating system compatibility.

✅ Supported – The platform is supported for this version of Redis Software and Redis Stack modules.

:warning: Deprecation warning – The platform is still supported for this version of Redis Software, but support will be removed in a future release.

Known issues

- RS131972: Creating an ACL that contains a line break in the Cluster Manager UI can cause shard migration to fail due to ACL errors.

Known limitations

#### Upload modules before OS upgrade

If the cluster contains any databases that use modules, you must upload module packages for the target OS version to a node in the existing cluster before you upgrade the cluster's operating system.

See [Upgrade a cluster's operating system]() for detailed upgrade instructions.

#### New 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.

- Search and export the log.

#### RedisGraph prevents upgrade to RHEL 9

You cannot upgrade from a prior RHEL version to RHEL 9 if the Redis Software cluster contains a RedisGraph module, even if unused by any database. The [RedisGraph module has reached End-of-Life](https://redis.com/blog/redisgraph-eol/) and is completely unavailable in RHEL 9.

#### Query results might include hash keys with lazily expired fields

If one or more fields of a hash key expire after an `FT.SEARCH` or `FT.AGGREGATE` query begins, Redis does not account for these lazily expired fields. As a result, keys with expired fields might still be included in the query results, leading to potentially incorrect or inconsistent results.

Security

#### Open source Redis security fixes compatibility

As part of Redis's commitment to security, Redis Software implements the latest [security fixes](https://github.com/redis/redis/releases) available with [open source Redis](https://github.com/redis/redis). Redis Software has already included the fixes for the relevant CVEs.

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