SCA: security update for rack (GHSA-7mqq-6cf9-v2qp)

medium Tenable Cloud Security Plugin ID 439699

Description

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

 - Rack is a modular Ruby web server interface. Prior to versions 2.2.23, 3.1.21, and 3.2.6, Rack::Directory
 interpolates the configured root path directly into a regular expression when deriving the displayed
 directory path. If root contains regex metacharacters such as +, *, or ., the prefix stripping can fail
 and the generated directory listing may expose the full filesystem path in the HTML output. This issue has
 been patched in versions 2.2.23, 3.1.21, and 3.2.6. (CVE-2026-34763)

Solution

Update the rack library and its related packages to version 2.2.23 or later.
