SCA: security update for msgpack5 (GHSA-qw35-55vc-rhgj)

low Tenable Cloud Security Plugin ID 473903

Description

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

- msgpack5 is a msgpack v5 implementation for node.js and the browser. Prior to 6.1.0, decoding a negative
signed 64-bit integer modifies the corresponding bytes in the caller-provided input buffer while computing
the value. Applications that retain or reuse encoded input for integrity checks, logging, or later
processing can observe silently corrupted data, while positive integers and other MessagePack value types
are unaffected. This issue is fixed in version 6.1.0. (CVE-2026-107296)

Solution

Update the msgpack5 library and its related packages to version 6.1.0 or later.
