SCA: security update for actionpack (GHSA-5hq2-xf89-9jxq)

medium Tenable Cloud Security Plugin ID 410867

Description

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

 - The actionpack ruby gem before 6.1.3.2 suffers from a possible open redirect vulnerability. Specially
 crafted Host headers in combination with certain "allowed host" formats can cause the Host Authorization
 middleware in Action Pack to redirect users to a malicious website. This is similar to CVE-2021-22881.
 Strings in config.hosts that do not have a leading dot are converted to regular expressions without proper
 escaping. This causes, for example, `config.hosts << "sub.example.com"` to permit a request with a Host
 header value of `sub-example.com`. (CVE-2021-22903)
