SCA: security update for puma (GHSA-2vqw-3mp8-cgmx)

high Tenable Cloud Security Plugin ID 478213

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, Puma is vulnerable
 to source IP spoofing when set_remote_address proxy_protocol: :v1 is enabled and persistent connections
 are used because Puma incorrectly re-parses PROXY protocol headers after each keep-alive request on the
 same connection, allowing an attacker to inject a second PROXY header and overwrite REMOTE_ADDR. This
 issue is fixed in versions 7.2.1 and 8.0.2. (CVE-2026-47737)

Solution

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