CVE-2025-32023 [HIGH] CVE-2025-32023: Redis is an open source, in-memory database that persists on disk 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

CVE-2025-48367 [HIGH] CVE-2025-48367: Redis is an open source, in-memory database that persists on disk 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-2025-49112 [LOW] CVE-2025-49112: setDeferredReply in networking setDeferredReply in networking.c in Valkey through 8.1.1 has an integer underflow for prev->size - prev->used.

CVE-2025-27151 [CRITICAL] CVE-2025-27151: Redis is an open source, in-memory database that persists on disk 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 b

CVE-2025-21605 [HIGH] CWE-770 CVE-2025-21605: Redis is an open source, in-memory database that persists on disk. In versions starting at 2.6 and p 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-lim

CVE-2024-46981 [CRITICAL] CVE-2024-46981: Redis is an open source, in-memory database that persists on disk 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 Lu

CVE-2024-51741 [MEDIUM] CVE-2024-51741: Redis is an open source, in-memory database that persists on disk 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-2024-31449 [HIGH] CVE-2024-31449: Redis is an open source, in-memory database that persists on disk 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 upg

CVE-2024-31228 [MEDIUM] CVE-2024-31228: Redis is an open source, in-memory database that persists on disk 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 proces

CVE-2024-31227 [MEDIUM] CVE-2024-31227: Redis is an open source, in-memory database that persists on disk 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.
