CVE-2026-53962: Nokogiri Insecure Xml Sanitization
A Nokogiri-based XML/SVG sanitizer removes tags or attributes but fails to remove internal/external XML subsets or entity references. This allows an attacker to hide XSS payloads inside XML entities (`<!ENTITY ...>`) that seamlessly bypass the tag/attribute blocklist. Ensure you remove `internal_subset`, `external_subset`, and nodes of type `Nokogiri::XML::N
