https://notcve.org/view.php?id=CVE-2025-48367
07 Jul 2025 — 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. • https://github.com/redis/redis/commit/bde62951accfc4bb0a516276fd0b4b307e140ce2 • CWE-770: Allocation of Resources Without Limits or Throttling •

CVE-2025-32023 – Redis allows out of bounds writes in hyperloglog commands leading to RCE
https://notcve.org/view.php?id=CVE-2025-32023
07 Jul 2025 — 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 ... • https://github.com/leesh3288/CVE-2025-32023 • CWE-680: Integer Overflow to Buffer Overflow •

CVE-2025-27151 – redis-check-aof may lead to stack overflow and potential RCE
https://notcve.org/view.php?id=CVE-2025-27151
29 May 2025 — 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. This update for valkey fixes the following issues. • https://github.com/redis/redis/security/advisories/GHSA-5453-q98w-cmvm • CWE-20: Improper Input Validation CWE-121: Stack-based Buffer Overflow •

CVE-2025-21605 – Redis DoS Vulnerability due to unlimited growth of output buffers abused by unauthenticated client
https://notcve.org/view.php?id=CVE-2025-21605
23 Apr 2025 — 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. • https://github.com/redis/redis/releases/tag/7.4.3 • CWE-770: Allocation of Resources Without Limits or Throttling •

CVE-2024-51741 – Redis allows denial-of-service due to malformed ACL selectors
https://notcve.org/view.php?id=CVE-2024-51741
06 Jan 2025 — 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. Redis es una base de datos en memoria de código abierto que persiste en el disco. Un usuario autenticado con privilegios suficientes puede crear un selector de ACL mal formado que, cuando se accede a él, desencadena un pánico del servidor... • https://github.com/redis/redis/security/advisories/GHSA-prpq-rh5h-46g9 • CWE-20: Improper Input Validation •

CVE-2024-31227 – Denial-of-service due to malformed ACL selectors in Redis
https://notcve.org/view.php?id=CVE-2024-31227
07 Oct 2024 — 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. • https://github.com/redis/redis/commit/b351d5a3210e61cc3b22ba38a723d6da8f3c298a • CWE-20: Improper Input Validation •

CVE-2024-31228 – Denial-of-service due to unbounded pattern matching in Redis
https://notcve.org/view.php?id=CVE-2024-31228
07 Oct 2024 — 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. • https://github.com/redis/redis/commit/9317bf64659b33166a943ec03d5d9b954e86afb0 • CWE-674: Uncontrolled Recursion •

07 Oct 2024 — 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.

CVE-2023-41056 – Redis vulnerable to integer overflow in certain payloads
https://notcve.org/view.php?id=CVE-2023-41056
10 Jan 2024 — Redis is an in-memory database that persists on disk. Redis incorrectly handles resizing of memory buffers which can result in integer overflow that leads to heap overflow and potential remote code execution. This issue has been patched in version 7.0.15 and 7.2.4. Redis es una base de datos en memoria que persiste en el disco. Redis maneja incorrectamente el cambio de tamaño de los búferes de memoria, lo que puede provocar un desbordamiento de enteros que provoca un desbordamiento del montón y una posible ... • https://github.com/redis/redis/releases/tag/7.0.15 • CWE-190: Integer Overflow or Wraparound CWE-762: Mismatched Memory Management Routines •

CVE-2023-45145 – Redis Unix-domain socket may have be exposed with the wrong permissions for a short time window.
https://notcve.org/view.php?id=CVE-2023-45145
18 Oct 2023 — Redis is an in-memory database that persists on disk. On startup, Redis begins listening on a Unix socket before adjusting its permissions to the user-provided configuration. If a permissive umask(2) is used, this creates a race condition that enables, during a short period of time, another process to establish an otherwise unauthorized connection. This problem has existed since Redis 2.6.0-RC1. This issue has been addressed in Redis versions 7.2.2, 7.0.14 and 6.2.14. • https://github.com/redis/redis/commit/03345ddc7faf7af079485f2cbe5d17a1611cbce1 • CWE-269: Improper Privilege Management CWE-668: Exposure of Resource to Wrong Sphere •
