AI-powered analysis for quick understanding

This vulnerability allows a malicious user to inject harmful data into the responses sent to clients, which can corrupt or alter the information other users receive on the same connection. It affects specific versions of the Valkey database, and the issue arises from improper handling of errors in scripting commands.

Technical Description

Valkey is a distributed key-value database. Prior to versions 9.0.2, 8.1.6, 8.0.7, and 7.2.12, a malicious user can use scripting commands to inject arbitrary information into the response stream for the given client, potentially corrupting or returning tampered data to other users on the same connection. The error handling code for lua scripts does not properly handle null characters. Versions 9.0.2, 8.1.6, 8.0.7, and 7.2.12 fix the issue.
