SCA: security update for rack (GHSA-7wqh-767x-r66v)

high Tenable Self-Hosted Container Security Plugin ID 421070

Description

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

 - Rack provides an interface for developing web applications in Ruby. Prior to versions 2.2.13, 3.0.14, and
 3.1.12, `Rack::Static` can serve files under the specified `root:` even if `urls:` are provided, which may
 expose other files under the specified `root:` unexpectedly. The vulnerability occurs because
 `Rack::Static` does not properly sanitize user-supplied paths before serving files. Specifically, encoded
 path traversal sequences are not correctly validated, allowing attackers to access files outside the
 designated static file directory. By exploiting this vulnerability, an attacker can gain access to all
 files under the specified `root:` directory, provided they are able to determine then path of the file.
 Versions 2.2.13, 3.0.14, and 3.1.12 contain a patch for the issue. Other mitigations include removing
 usage of `Rack::Static`, or ensuring that `root:` points at a directory path which only contains files
 which should be accessed publicly. It is likely that a CDN or similar static file server would also
 mitigate the issue. (CVE-2025-27610)
