Impact	CVSS 7.0, EPSS 75.7%, PoC available. Redis is one of the most widely deployed in-memory databases. While authentication is required, many Redis instances use weak or default passwords, and the AUTH command is often disabled in development environments. RCE on Redis servers exposes cached session data, application state, and potentially the entire server.
Exploit ScenarioDerived	An attacker gains Redis access through a weak password or SSRF vulnerability. They send a crafted EVAL command with a Lua script designed to trigger the UAF condition. Through heap manipulation, they achieve arbitrary code execution on the Redis server. They extract cached session tokens, authentication data, and use the server as a pivot point for lateral movement.

AnalysisAIv1 – Mar 28, 2026

Redis versions prior to 7.4.2, 7.2.7, and 6.2.17 contain a use-after-free vulnerability in the Lua scripting engine that allows authenticated users to achieve remote code execution. By manipulating the garbage collector through crafted Lua scripts, attackers can corrupt memory and execute arbitrary code on the Redis server.

Earlier versions of this analysis (1)

v1 Mar 28, 2026 - 18:02 CVSS 7.0

Use-after-free in Redis Lua engine via garbage collector manipulation allows authenticated remote code execution.

RemediationAI

Update Redis to 7.4.2, 7.2.7, or 6.2.17. Disable Lua scripting if not required (rename EVAL/EVALSHA commands). Require strong authentication with AUTH and ACLs. Restrict Redis network exposure to trusted application servers only. Monitor for unusual EVAL command patterns.

Checking this CVE against your own stacks and servers is part of the Basic plan and up.

Technical ContextAI · show details

Redis includes a Lua scripting engine (EVAL/EVALSHA commands) for server-side script execution. A vulnerability in how the Lua garbage collector interacts with Redis objects allows an authenticated user to craft a Lua script that triggers a use-after-free condition. By carefully controlling memory layout and garbage collection timing, an attacker can corrupt function pointers and redirect execution to attacker-controlled code.

DescriptionGitHub Advisory

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.

Executive ViewAI

Why It Matters

Organizations using Redis face moderate risk from CVE-2024-46981, a use-after-free vulnerability rated CVSS 7.0. Exploitation could compromise the security of affected deployments. With an EPSS score of 76%, this vulnerability faces very high likelihood of exploitation. Organizations should apply vendor updates when available and consider compensating controls in the interim.

Business Impact: Severe

Compensating Controls

Apply vendor patch. If immediate patching is not feasible: (1) Enable ASLR and DEP where available; (2) Implement network segmentation; (3) Monitor for exploitation indicators.

Attack Technique

Use After Free HIGH

Use-after-free vulnerabilities occur when a program continues to access memory through a pointer after that memory has been deallocated.

Memory Corruption HIGH

Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.

Remote Code Execution CRITICAL

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
