CVE-2026-9487

XML::Sig versions before 0.71 for Perl allow signature wrapping via duplicate ID. getsignedxml in lib/XML/Sig.pm, called from verify, resolves the SignedInfo Reference/@URI to a node with the XPath expression "//@ID='$id'" and returns the first node of the resulting node set. A document in which...

CVE-2026-9390

XML::Sig versions before 0.71 for Perl allow XPath injection in ID lookup. verify and getsignedxml in lib/XML/Sig.pm build XPath expressions by concatenating the SignedInfo/Reference/@URI value read from the document being verified. The value is neither escaped nor checked against the NCName...

CVE-2026-18092

Net::SAML2 versions before 0.86 for Perl allow SAML authentication bypass via XML signature wrapping because newfromxml reads assertion identity with document-wide XPath instead of the signed subtree. newfromxml reads the NameID, attribute values, SessionIndex, audience and other identity fields...

CVE-2026-18089

Net::SAML2 versions before 0.86 for Perl allow SAML authentication bypass by verifying responses against the response-embedded certificate in verifyxml when no trust anchor is configured. verifyxml in Net::SAML2::Role::VerifyXML runs "return if !$anchors && !$cacert;" as soon as the XML::Sig chec...

CVE-2026-18092

Perl's Net::SAML2 versions before 0.86 are vulnerable to a SAML authentication bypass via XML signature wrapping . The root cause is that the new_from_xml function retrieves identity fields (such as NameID and attributes) using document-wide XPath queries instead of restricting the search to the ...

CVE-2026-9487

Versions of the XML::Sig Perl module prior to 0.71 are vulnerable to signature wrapping due to an improper handling of duplicate IDs. The root cause resides in the _get_signed_xml() function within lib/XML/Sig.pm, which resolves the SignedInfo Reference/@URI to a node using the XPath expression /...
