SCA: security update for io.netty:netty-codec-redis (GHSA-rgrr-p7gp-5xj7)

high Tenable Self-Hosted Container Security Plugin ID 441341

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and
4.1.133.Final, the Netty Redis codec encoder (RedisEncoder) writes user-controlled string content directly
to the network output buffer without validating or sanitizing CRLF (\r\n) characters. Since the Redis
Serialization Protocol (RESP) uses CRLF as the command/response delimiter, an attacker who can control the
content of a Redis message can inject arbitrary Redis commands or forge fake responses. This vulnerability
is fixed in 4.2.13.Final and 4.1.133.Final. (CVE-2026-42586)

Solution

Update the io.netty:netty-codec-redis library and its related packages to version 4.1.133.Final or later.
