CVE-2026-18568

XML::Sig versions from 0.29 before 0.72 for Perl allow signature verification bypass because verify returns true when every signature was skipped before any cryptographic check. verify in lib/XML/Sig.pm counts the //dsig:Signature elements into $numsigs and iterates over them, but two paths reach...

CVE-2026-18568

XML::Sig for Perl versions prior to 0.72 is vulnerable: verify() can return true without performing any digest or signature checks when multiple signatures are present or id_attr mismatch occurs, effectively bypassing signature verification. Affected range includes 0.29–0.71 (up to 0.28 is not af...

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-2026-18092 Net::SAML2 versions before 0.86 for Perl allow SAML authentication bypass via XML signature wrapping because new_from_xml reads assertion identity with document-wide XPath instead of the signed subtree

CVE-2026-18092

Net::SAML2 for Perl is affected prior to version 0.86. The vulnerability arises because new_from_xml reads assertion identity (NameID, attributes, SessionIndex, etc.) using document-wide XPath (e.g., //saml:Assertion/saml:AttributeStatement/saml:Attribute, //saml:Subject/saml:NameID) instead of t...

CVE-2026-9487

CVE-2026-9487 affects XML::Sig for Perl up to version 0.70. The vulnerability arises because _get_signed_xml() resolves IDs with the XPath //*[@ID='$id'] and accepts two elements sharing the same ID, causing signature wrapping: the digest and signature are validated against the first element in d...

CVE-2026-9487 XML::Sig versions before 0.71 for Perl allow signature wrapping via duplicate ID

CVE-2026-9390

CVE-2026-9390 affects XML::Sig (Perl) versions before 0.71. The issue arises when verify()/_get_signed_xml() build XPath expressions by concatenating SignedInfo/Reference/@URI from the document without escaping or enforcing NCName rules. A URI containing a single quote can terminate the string li...

CVE-2026-54783 CoreWCF: XML Signature Wrapping in WS-Security endorsing/supporting signature verification allows replay of captured signed messages

CoreWCF is a port of the service side of Windows Communication Foundation WCF to .NET Core. Prior to 1.8.1 and 1.9.1, CoreWCF WS-Security endorsing and supporting signature verification does not ensure the selected ds:Signature covers the expected Security header target, allowing an attacker with...

CVE-2026-54783

CoreWCF (Net Core port of WCF) has an XML Signature Wrapping vulnerability in WS-Security endorsing/signature verification prior to v1.8.1 and v1.9.1, where the ds:Signature may not cover the expected Security header target. An attacker who captures a signed SOAP envelope can replay arbitrary ser...
