CSIRTS triage

What: An authenticated user can exhaust server memory by sending multi-bulk commands with many bulks, as the server allocates memory for all command arguments even when the command is skipped due to insufficient permissions.
Who is affected: Redis deployments 8.0.3 and earlier with untrusted authenticated users.
Urgency: Low severity (CVSS 3.5) and not exploited; only affects authenticated attackers and does not grant unauthorized access.
Action: Upgrade to Redis version after 8.0.3 or restrict authentication to trusted users only.
