CVE-2026-18108

Net::SAML2 versions before 0.86 for Perl allow authentication bypass because verifyencryptedassertion accepts an EncryptedAssertion whose decrypted content carries no signature. verifyencryptedassertion decrypts the EncryptedAssertion and returns it as verified when it carries no signature, via...

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-2026-18108

CVE-2026-18108 affects Net::SAML2 for Perl, before version 0.86. The vulnerability arises when _verify_encrypted_assertion decrypts an EncryptedAssertion and returns it as verified if there is no dsig:Signature; signature/trust checks run only when a signature exists. As a result, an unsigned dec...

CVE-2026-67298

FreeRDP versions 3.28.0 and earlier contain a heap buffer overflow in the server-side RAIL channel handler railserverhandlemessages in channels/rail/server/railmain.c. When processing a RAIL PDU header, the code subtracts RAILPDUHEADERLENGTH from the peer-controlled orderLength field without firs...

CVE-2026-67336

CVE-2026-67336 affects better-auth versions before 1.6.11, specifically the oidcProvider and mcp plugins. The root cause is insecure cryptographic defaults that advertise the none algorithm and allow plain PKCE by default. This can enable an attacker to exploit algorithm negotiation to accept uns...
