NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby3.4-rails-7.1 package and not the ruby3.4-rails-7.1 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

Nokogiri versions before 1.19.1 fail to check the return value from xmlC14NExecute in the canonicalize method, returning an empty string on failure instead of raising an exception. Attackers can exploit this to bypass signature validation in downstream SAML libraries by providing invalid canonicalized XML that is incorrectly accepted as valid.
