title: Known issues

title: Known limitations

text:
#### 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.

#### 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 7.8.6-256 supports open source Redis 7.4, 7.2, and 6.2. Below is the list of open source Redis CVEs and other security vulnerabilities fixed by version.

#### 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 7.8.6-95 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-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.

- (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-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 7.0.13)

- (CVE-2023-36824) Extracting key names from a command and a list of arguments may, in some cases, trigger a heap overflow and result in reading random heap memory, heap corruption, and potentially remote code execution. Specifically: using `COMMAND GETKEYS*` and validation of key names in ACL rules. (Redis 7.0.12)

- (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 6.2.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.

title: Version changes

text:
- [`POST /v1/cluster/actions/change_master`]() REST API requests will no longer allow a node that exists but is not finished bootstrapping to become the primary node. Such requests will now return the status code `406 Not Acceptable`.

- Node status now returns the actual provisional RAM and flash values even when the maximum number of shards on the node (`max_redis_servers`) is reached. Previously, the API returned 0 for `provisional_ram_of_node` and `provisional_flash_of_node` when a node reached its shard limit. This change affects REST API node status requests and the `rladmin status nodes` command's output.

title: Breaking changes

text:
- Upgrading to Redis Software version 8.0.10 through 8.0.16-29 can cause LDAP authentication to fail with "certificate signed by unknown authority" errors if your cluster currently uses LDAP authentication. This issue was fixed in [Redis Software version 8.0.16-33]().

- For Redis Software versions 8.0.2 through 8.0.10, LDAP filters for `user_dn_query` and `dn_group_query` strictly require parentheses to function correctly. Filters that previously worked without parentheses will no longer work after upgrading to these versions. For example, you must include the parentheses in `(sAMAccountName=%u)`. As of version 8.0.16, this breaking change no longer applies, and both `(sAMAccountName=%u)` and `sAMAccountName=%u` are valid filters.

- Redis Software installation script changes:

    - Changed the `--skip-updating-env-path` option to `--update-env-path` when running [`install.sh`]().

    - Changed the `skip_updating_env_path` parameter to `update_env_path` in the [installation answers file]().

title: Redis database version 8 breaking changes {#redis-8-breaking-changes}

text:
When new major versions of Redis Open Source change existing commands, upgrading your database to a new version can potentially break some functionality. Before you upgrade, read the provided list of breaking changes that affect Redis Software and update any applications that connect to your database to handle these changes.

#### ACL behavior changes

Before Redis 8, the existing [ACL]() categories `@read`, `@write`, `@dangerous`, `@admin`, `@slow`, and `@fast` did not include commands for Redis Search and the JSON, time series, and probabilistic data structures.

Starting with Redis 8, Redis includes all Query Engine, JSON, time series, Bloom filter, cuckoo filter, top-k, count-min sketch, and t-digest commands in these existing ACL categories.

As a result:

- Existing ACL rules such as `+@read +@write` will allow access to more commands than in previous versions of Redis. Here are some examples:

  - A user with `+@read` access will be able to execute `FT.SEARCH`.

  - A user with `+@write` access will be able to execute `JSON.SET`.

- ACL rules such as `+@all -@write`  will allow access to fewer commands than previous versions of Redis.

  - For example, a user with `+@all -@write` will not be able to execute `JSON.SET`.

  - Explicit inclusion of new [command categories]() is required to maintain access. The new categories are: `@search`, `@json`, `@timeseries`, `@bloom`, `@cuckoo`, `@topk`, `@cms`, and `@tdigest`.

- ACL rules such as `+@read +JSON.GET` can now be simplified as `+@read` because `JSON.GET` is included in the `@read` category.

Note that the `@all` category did not change, as it always included all the commands.

#### Redis Search changes

The following changes affect behavior and validation in Redis Search:

- Enforces validation for `LIMIT` arguments (offset must be 0 if limit is 0).

- Enforces parsing rules for `FT.CURSOR READ` and `FT.ALIASADD`.

- Parentheses are now required for exponentiation precedence in `APPLY` expressions.

- Invalid input now returns errors instead of empty results.

- Default values revisited for reducers like `AVG`, `COUNT`, `SUM`, `STDDEV`, `QUANTILE`, and others.

- Updates to scoring (`BM25` is now the default instead of `TF-IDF`).

- Improved handling of expired records, memory constraints, and malformed fields.

title: Deprecations

text:
#### API deprecations

- Deprecated the `policy` field for [bootstrap]() REST API requests. Use [`PUT /v1/cluster/policy`]() to change cluster policies after cluster creation instead.

- Deprecated the `module_args` field for [database]() REST API requests. Use the new module configuration objects `search`, `timeseries`, and `probabilistic` instead.

- Deprecated `event_archive_cleanup_task_settings` for `job_scheduler` REST API requests.

#### Redis Search deprecations

- Deprecated commands: `FT.ADD`, `FT.SAFEADD`, `FT.DEL`, `FT.GET`, `FT.MGET`, `FT.SYNADD`, `FT.DROP`, `FT._DROPIFX`, and `FT.CONFIG`.

- Deprecated `FT.SEARCH` options: `GEOFILTER`, `FILTER`, and `NOSTOPWORDS`.

- Deprecated vector search options: `INITIAL_CAP` and `BLOCK_SIZE`.

- Deprecated configuration parameters: `WORKER_THREADS`, `MT_MODE`, `PRIVILEGED_THREADS_NUM`, and `GCSCANSIZE`.

- Deprecated dialects: `DIALECT 1`, `DIALECT 3`, and `DIALECT 4`.

#### Internal monitoring and v1 Prometheus metrics deprecation

The existing [internal monitoring engine]() is deprecated. We recommend transitioning to the new [metrics stream engine]() for improved performance, enhanced integration capabilities, and modernized metrics streaming.

V1 Prometheus metrics are deprecated but still available. To transition to the new metrics stream engine, either migrate your existing dashboards using [this guide]() or use [new preconfigured dashboards]().

As part of the transition to the metrics stream engine, some internal cluster manager alerts were deprecated in favor of external monitoring solutions. See the [alerts transition plan]() for guidance.

title: Known issues

text:
- RS180550: You cannot set up SSO when the Cluster Manager UI is exposed through an IPv6-based load balancer or gateway.

    As a workaround, use an IPv4-based address for the SSO service base address, or register a DNS name that resolves to the IPv6 address.

    This issue was fixed in Redis Software version 8.0.10.

- RS131972: Creating an ACL that contains a line break in the Cluster Manager UI can cause shard migration to fail due to ACL errors. This issue was fixed in Redis Software version 8.0.6.

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

title: Known limitations

text:
#### 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.

#### 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.
