Action Pack is a framework for handling and responding to web requests. Starting in version 4.0.0 and prior to versions 6.1.7.9, 7.0.8.5, 7.1.4.1, and 7.2.1.1, there is a possible ReDoS vulnerability in Action Controller's HTTP Token authentication. For applications using HTTP Token authentication via `authenticate_or_request_with_http_token` or similar, a carefully crafted header may cause header parsing to take an unexpected amount of time, possibly resulting in a DoS vulnerability. All users running an affected release should either upgrade to versions 6.1.7.9, 7.0.8.5, 7.1.4.1, or 7.2.1.1 or apply the relevant patch immediately. One may choose to use Ruby 3.2 as a workaround.Ruby 3.2 has mitigations for this problem, so Rails applications using Ruby 3.2 or newer are unaffected. Rails 8.0.0.beta1 depends on Ruby 3.2 or greater so is unaffected.

The remote Debian 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5881 advisory.

    Multiple security issues were discovered in the Rails web framework     which could result cross-site scripting, information disclosure, denial     of service or bypass of content security policies.

    For the stable distribution (bookworm), these problems have been fixed in     version 2:6.1.7.10+dfsg-1~deb12u1.

    We recommend that you upgrade your rails packages.

    For the detailed security status of rails please refer to     its security tracker page at:
