Recent Redis Security Vulnerabilities

CVE	Date	Vulnerability	Products
CVE-2026-25243	May 05, 2026	Redis 8.6.3up RCE via RESTORE (bad payloads) Redis is an in-memory data structure store. In versions of redis-server up to 8.6.3, the RESTORE command does not properly validate serialized values. An authenticated attacker with permission to execute RESTORE can supply a crafted serialized payload that triggers invalid memory access and may lead to remote code execution. A workaround is to restrict access to the RESTORE command with ACL rules. This is patched in version 8.6.3.	Redis
CVE-2026-23631	May 05, 2026	Auth RCE via UAF in Redis Lua master-replica sync fixed in 8.6.3 Redis is an in-memory data structure store. In all versions of redis-server with Lua scripting, an authenticated attacker can exploit the master-replica synchronization mechanism to trigger a use-after-free on replicas where replica-read-only is disabled or can be disabled, which may lead to remote code execution. A workaround is to prevent users from executing Lua scripts or avoid using replicas where replica-read-only is disabled. This is patched in version 8.6.3.	Redis
CVE-2026-23479	May 05, 2026	Redis 7.2.0-8.6.3: Unblock Client Flow UAF leads to RCE Redis is an in-memory data structure store. In redis-server from 7.2.0 until 8.6.3, the unblock client flow does not handle an error return from `processCommandAndResetClient` when re-executing a blocked command. If a blocked client is evicted during this flow, an authenticated attacker can trigger a use-after-free that may lead to remote code execution. This has been patched in version 8.6.3.	Redis
CVE-2025-62507	Nov 04, 2025	Redis XACKDEL stack buffer overflow CVE-2025-62507 (8.2.0-8.2.2) Redis is an open source, in-memory database that persists on disk. In versions 8.2.0 and above, a user can run the XACKDEL command with multiple ID's and trigger a stack buffer overflow, which may potentially lead to remote code execution. This issue is fixed in version 8.2.3. To workaround this issue without patching the redis-server executable is to prevent users from executing XACKDEL operation. This can be done using ACL to restrict XACKDEL command.	Redis
CVE-2025-49844	Oct 03, 2025	Redis 8.2 UGAF: Lua Script UAF RCE (fixed 8.2.2) Redis is an open source, in-memory database that persists on disk. Versions 8.2.1 and below allow an authenticated user to use a specially crafted Lua script to manipulate the garbage collector, trigger a use-after-free and potentially lead to remote code execution. The problem exists in all versions of Redis with Lua scripting. This issue is fixed in version 8.2.2. To workaround this issue 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.	Redis
CVE-2025-46819	Oct 03, 2025	Redis 8.2.1 Auth'd Lua Script OOB Read/Crash via EVAL/FUNCTION (8.2.2 Fix) Redis is an open source, in-memory database that persists on disk. Versions 8.2.1 and below allow an authenticated user to use a specially crafted LUA script to read out-of-bound data or crash the server and subsequent denial of service. The problem exists in all versions of Redis with Lua scripting. This issue is fixed in version 8.2.2. To workaround this issue without patching the redis-server executable is to prevent users from executing Lua scripts. This can be done using ACL to block a script by restricting both the EVAL and FUNCTION command families.	Redis
CVE-2025-46818	Oct 03, 2025	Redis 8.2.1 and below: Auth user can run Lua scripts & execute code Redis is an open source, in-memory database that persists on disk. Versions 8.2.1 and below allow an authenticated user to use a specially crafted Lua script to manipulate different LUA objects and potentially run their own code in the context of another user. The problem exists in all versions of Redis with LUA scripting. This issue is fixed in version 8.2.2. A 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 block a script by restricting both the EVAL and FUNCTION command families.	Redis
CVE-2025-46817	Oct 03, 2025	Redis <8.2.2 Integer Overflow via Lua Script RCE Redis is an open source, in-memory database that persists on disk. Versions 8.2.1 and below allow an authenticated user to use a specially crafted Lua script to cause an integer overflow and potentially lead to remote code execution The problem exists in all versions of Redis with Lua scripting. This issue is fixed in version 8.2.2.	Redis
CVE-2025-46686	Jul 23, 2025	Redis 8.0.3 Multi-Bulk Authenticated Memory Exhaustion 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.	Redis
CVE-2025-32023	Jul 07, 2025	Redis hyperloglog OOB write -> RCE (2.8–8.0.x) 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.	Redis
