CVE-2025-46686 (opens in a new tab)How to fix?
There is no fixed version for Ubuntu:20.04 redis.
NVD Description
Note: Versions mentioned in the description apply only to the upstream redis package and not the redis package as distributed by Ubuntu.
See How to fix? for Ubuntu:20.04 relevant fixed versions and status.
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.
