USN-8770-1: SimpleSAMLphp vulnerabilities

It was discovered that SimpleSAMLphp incorrectly validated cryptographic signatures in XML messages. An authenticated attacker could possibly use this issue to impersonate users or gain elevated privileges. This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. CVE-2019-3465 It was...

CVE-2026-89043

passport-saml-encrypted through 0.1.13 contains an XML signature wrapping vulnerability where signature verification and assertion extraction use independent XPath lookups with no cross-validation. Attackers holding any validly signed SAML message can prepend a forged unsigned assertion that gets...

CVE-2026-89043

passport-saml-encrypted through version 0.1.13 is affected by an XML signature wrapping vulnerability. The root cause is that signature verification and assertion extraction use independent XPath lookups with no cross-validation (see saml.js lines 256 and 328). An attacker holding any validly sig...

CVE-2026-49289

The SimpleSAMLphp SAML2 library is a PHP library for SAML2 related functionality. In 4.19.2 and 4.20.2, the library permits attacker-controlled XPath transforms while processing XML signatures in specially crafted SAML messages. XPath evaluation can consume uncontrolled processing resources,...

CVE-2026-49289

The simplesamlphp/saml2 library (versions 4.19.2 and 4.20.2) permits attacker-controlled XPath transforms during XML signature processing, allowing a remote unauthenticated attacker to consume excessive resources and cause denial of service. The fix caps transform count and rejects XPath transfor...

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...
