redis

Redis through 7.4.3 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.

CVE-2025-46686 is a vulnerability affecting Redis versions up to 7.4.3, where an authenticated user can cause excessive memory consumption by sending a multi-bulk command composed of many bulks. The root cause lies in the Redis server's memory allocation behavior: it allocates memory for the command arguments of every bulk in the multi-bulk command, even when the command is skipped due to insufficient permissions. This means that despite the user lacking the necessary permissions to execute certain commands, the server still allocates memory for the arguments of those commands, leading to potential memory exhaustion. This vulnerability can be exploited by an authenticated attacker who can send crafted multi-bulk commands to the Redis server, potentially leading to denial of service (DoS) conditions due to resource exhaustion. Since the vulnerability requires authentication, exploitation is limited to users who already have some level of access to the Redis instance. However, Redis is often deployed in environments where authentication might be weak or misconfigured, increasing the risk. No known exploits are currently reported in the wild, and no CVSS score has been assigned yet. The lack of a patch link indicates that a fix might not be publicly available at the time of publication, emphasizing the need for immediate mitigation steps by administrators.
