Rails has a possible XSS vulnerability in its Action Pack debug exceptions

Action Pack is a Rubygem for building web applications on the Rails framework. In versions on the 8.1 branch prior to 8.1.2.1, the debug exceptions page does not properly escape exception messages. A carefully crafted exception message could inject arbitrary HTML and JavaScript into the page, leading to XSS. This affects applications with detailed exception pages enabled (`config.consider_all_requests_local = true`), which is the default in development. Version 8.1.2.1 contains a patch.

rubygem-actionpack: Open Redirect Vulnerability in Action Controller

An open redirect vulnerability is fixed in Rails 7.0.4.1 with the new protection against open redirects from calling redirect_to with untrusted user input. In prior versions the developer was fully responsible for only providing trusted input. However the check introduced could allow an attacker to bypass with a carefully crafted URL resulting in an open redirect vulnerability.
