CVE-2025-66568

CVE-2025-66568 affects the ruby-saml library (client-side SAML) with versions up to 1.12.4 vulnerable to authentication bypass via libxml2 canonicalization used by Nokogiri. On invalid XML input, canonicalization can return an empty string, causing DigestValue to be computed over that empty strin...

EUVD-2025-201828

The ruby-saml library implements the client side of an SAML authorization. Versions up to and including 1.12.4, are vulnerable to authentication bypass through the libxml2 canonicalization process used by Nokogiri for document transformation, which allows an attacker to execute a Signature Wrappi...
