SCA: security update for rack (GHSA-625h-95r8-8xpm)

high Tenable Cloud Security Plugin ID 435431

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 version 2.2.18, Rack::QueryParser enforces its
 params_limit only for parameters separated by &, while still splitting on both & and ;. As a result,
 attackers could use ; separators to bypass the parameter count limit and submit more parameters than
 intended. Applications or middleware that directly invoke Rack::QueryParser with its default configuration
 (no explicit delimiter) could be exposed to increased CPU and memory consumption. This can be abused as a
 limited denial-of-service vector. This issue has been patched in version 2.2.18. (CVE-2025-59830)
