CVE-2025-32023 1 Redis 1 Redis 2025-09-05 7 High
Redis is an open source, in-memory database that persists on disk. From 2.8 to before 8.0.3, 7.4.5, 7.2.10, and 6.2.19, an authenticated user may use a specially crafted string to trigger a stack/heap out of bounds write on hyperloglog operations, potentially leading to remote code execution. The bug likely affects all Redis versions with hyperloglog operations implemented. This vulnerability is fixed in 8.0.3, 7.4.5, 7.2.10, and 6.2.19. An additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from executing hyperloglog operations. This can be done using ACL to restrict HLL commands.
CVE-2025-48367 1 Redis 1 Redis 2025-09-05 7.5 High
Redis is an open source, in-memory database that persists on disk. An unauthenticated connection can cause repeated IP protocol errors, leading to client starvation and, ultimately, a denial of service. This vulnerability is fixed in 8.0.3, 7.4.5, 7.2.10, and 6.2.19.
CVE-2025-21605 4 Debian, Lfprojects, Redhat and 1 more 9 Debian Linux, Valkey, Discovery and 6 more 2025-09-05 7.5 High
Redis is an open source, in-memory database that persists on disk. In versions starting at 2.6 and prior to 7.4.3, An unauthenticated client can cause unlimited growth of output buffers, until the server runs out of memory or is killed. By default, the Redis configuration does not limit the output buffer of normal clients (see client-output-buffer-limit). Therefore, the output buffer can grow unlimitedly over time. As a result, the service is exhausted and the memory is unavailable. When password authentication is enabled on the Redis server, but no password is provided, the client can still cause the output buffer to grow from "NOAUTH" responses until the system will run out of memory. This issue has been patched in version 7.4.3. An additional workaround to mitigate this problem without patching the redis-server executable is to block access to prevent unauthenticated users from connecting to Redis. This can be done in different ways. Either using network access control tools like firewalls, iptables, security groups, etc, or enabling TLS and requiring users to authenticate using client side certificates.
CVE-2024-51741 2 Redhat, Redis 2 Enterprise Linux, Redis 2025-09-05 4.4 Medium
Redis is an open source, in-memory database that persists on disk. An authenticated with sufficient privileges may create a malformed ACL selector which, when accessed, triggers a server panic and subsequent denial of service. The problem is fixed in Redis 7.2.7 and 7.4.2.
CVE-2024-46981 3 Debian, Redhat, Redis 8 Debian Linux, Discovery, Enterprise Linux and 5 more 2025-09-05 7 High
Redis is an open source, in-memory database that persists on disk. An authenticated user may use a specially crafted Lua script to manipulate the garbage collector and potentially lead to remote code execution. The problem is fixed in 7.4.2, 7.2.7, and 6.2.17. An additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from executing Lua scripts. This can be done using ACL to restrict EVAL and EVALSHA commands.
CVE-2024-31228 2 Redhat, Redis 3 Discovery, Enterprise Linux, Redis 2025-09-04 5.5 Medium
Redis is an open source, in-memory database that persists on disk. Authenticated users 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 crash. This problem has been fixed in Redis versions 6.2.16, 7.2.6, and 7.4.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2024-31449 2 Redhat, Redis 3 Discovery, Enterprise Linux, Redis 2025-09-04 7 High
Redis is an open source, in-memory database that persists on disk. 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. The problem exists in all versions of Redis with Lua scripting. This problem has been fixed in Redis versions 6.2.16, 7.2.6, and 7.4.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2025-46686 1 Redis 1 Redis 2025-08-26 3.5 Low
Redis through 8.0.3 allows memory consumption via a multi-bulk command composed of many bulks, sent by an authenticated user. This occurs because the server allocates memory for the command arguments of every bulk, even when the command is skipped because of insufficient permissions. NOTE: this is disputed by the Supplier because abuse of the commands network protocol is not a violation of the Redis Security Model.
CVE-2024-31227 2 Redhat, Redis 2 Enterprise Linux, Redis 2025-08-26 4.4 Medium
Redis is an open source, in-memory database that persists on disk. An authenticated with sufficient privileges may create a malformed ACL selector which, when accessed, triggers a server panic and subsequent denial of service. The problem exists in Redis 7 prior to versions 7.2.6 and 7.4.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2025-27151 1 Redis 1 Redis 2025-08-22 4.7 Medium
Redis is an open source, in-memory database that persists on disk. In versions starting from 7.0.0 to before 8.0.2, a stack-based buffer overflow exists in redis-check-aof due to the use of memcpy with strlen(filepath) when copying a user-supplied file path into a fixed-size stack buffer. This allows an attacker to overflow the stack and potentially achieve code execution. This issue has been patched in version 8.0.2.
CVE-2022-0543 3 Canonical, Debian, Redis 3 Ubuntu Linux, Debian Linux, Redis 2025-07-30 10.0 Critical

CVE-2022-31144 1 Redis 1 Redis 2025-04-23 7 High
Redis is an in-memory database that persists on disk. A specially crafted `XAUTOCLAIM` command on a stream key in a specific state may result with heap overflow, and potentially remote code execution. This problem affects versions on the 7.x branch prior to 7.0.4. The patch is released in version 7.0.4.
CVE-2022-35951 2 Fedoraproject, Redis 2 Fedora, Redis 2025-04-23 7 High
Redis is an in-memory database that persists on disk. Versions 7.0.0 and above, prior to 7.0.5 are vulnerable to an Integer Overflow. 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. This has been patched in Redis version 7.0.5. No known workarounds exist.
CVE-2022-24735 5 Fedoraproject, Netapp, Oracle and 2 more 6 Fedora, Management Services For Element Software, Management Services For Netapp Hci and 3 more 2025-04-22 3.9 Low
Redis is an in-memory database that persists on disk. By exploiting weaknesses in the Lua script execution environment, an attacker with access to Redis prior to version 7.0.0 or 6.2.7 can inject Lua code that will execute with the (potentially higher) privileges of another Redis user. The Lua script execution environment in Redis provides some measures that prevent a script from creating side effects that persist and can affect the execution of the same, or different script, at a later time. Several weaknesses of these measures have been publicly known for a long time, but they had no security impact as the Redis security model did not endorse the concept of users or privileges. With the introduction of ACLs in Redis 6.0, these weaknesses can be exploited by a less privileged users to inject Lua code that will execute at a later time, when a privileged user executes a Lua script. The problem is fixed in Redis versions 7.0.0 and 6.2.7. An additional workaround to mitigate this problem without patching the redis-server executable, if Lua scripting is not being used, is to block access to `SCRIPT LOAD` and `EVAL` commands using ACL rules.
CVE-2022-24736 5 Fedoraproject, Netapp, Oracle and 2 more 6 Fedora, Management Services For Element Software, Management Services For Netapp Hci and 3 more 2025-04-22 3.3 Low
Redis is an in-memory database that persists on disk. Prior to versions 6.2.7 and 7.0.0, an attacker attempting to load a specially crafted Lua script can cause NULL pointer dereference which will result with a crash of the redis-server process. The problem is fixed in Redis versions 7.0.0 and 6.2.7. An additional workaround to mitigate this problem without patching the redis-server executable, if Lua scripting is not being used, is to block access to `SCRIPT LOAD` and `EVAL` commands using ACL rules.
CVE-2022-3647 1 Redis 1 Redis 2025-04-15 3.1 Low
** DISPUTED ** A vulnerability, which was classified as problematic, was found in Redis up to 6.2.7/7.0.5. Affected is the function sigsegvHandler of the file debug.c of the component Crash Report. The manipulation leads to denial of service. The complexity of an attack is rather high. The exploitability is told to be difficult. The real existence of this vulnerability is still doubted at the moment. Upgrading to version 6.2.8 and 7.0.6 is able to address this issue. The patch is identified as 0bf90d944313919eb8e63d3588bf63a367f020a3. It is recommended to apply a patch to fix this issue. VDB-211962 is the identifier assigned to this vulnerability. NOTE: The vendor claims that this is not a DoS because it applies to the crash logging mechanism which is triggered after a crash has occurred.
CVE-2023-36824 2 Fedoraproject, Redis 2 Fedora, Redis 2025-04-10 7.4 High
Redis is an in-memory database that persists on disk. In Redit 7.0 prior to 7.0.12, 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. Several scenarios that may lead to authenticated users executing a specially crafted `COMMAND GETKEYS` or `COMMAND GETKEYSANDFLAGS`and authenticated users who were set with ACL rules that match key names, executing a specially crafted command that refers to a variadic list of key names. The vulnerability is patched in Redis 7.0.12.
CVE-2023-22458 2 Redhat, Redis 2 Enterprise Linux, Redis 2025-03-11 5.5 Medium
