SCA: security update for puma (GHSA-qpgp-93vx-g8v8)

high Tenable Cloud Security Plugin ID 478212

Description

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

 - Puma is a Ruby/Rack web server built for parallelism. From 5.5.0 until 7.2.1 and 8.0.2, when PROXY
 protocol v1 support is enabled, Puma reads incoming bytes into an internal buffer while waiting for CRLF
 to determine whether a PROXY v1 line is present, allowing an attacker that continuously sends bytes
 without CRLF to cause unbounded in-process memory growth and additional CPU cost from repeatedly scanning
 the growing buffer. This issue is fixed in versions 7.2.1 and 8.0.2. (CVE-2026-47736)

Solution

Update the puma library and its related packages to version 7.2.1 or later.
