PT-2026-67421

XML::Sig versions before 0.71 for Perl allow signature wrapping via duplicate ID. get signed xml 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 whic...

CVE-2026-69092: Improper Neutralization of Input During Web Page Generation

Admidio versions before 5.0.11 contain a reflected cross-site scripting vulnerability in the SSO/SAML endpoint that echoes unencoded exception messages to the HTTP response. Unauthenticated attackers can inject arbitrary JavaScript through SAML Issuer elements or LightSaml library parameters to...

CVE-2026-18092: Improper Verification of Cryptographic Signature

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...

PT-2026-67393

Name of the Vulnerable Software and Affected Versions Net::SAML2 versions prior to 0.86 Description An authentication bypass exists when no trust anchor is configured.

PT-2026-67395

Name of the Vulnerable Software and Affected Versions Net::SAML2 versions prior to 0.86 Description An authentication bypass exists because the verify encrypted assertion function accepts an EncryptedAssertion whose decrypted content lacks a signature. The function decrypts the EncryptedAssertion...

CVE-2026-67328 @better-auth/sso before 1.6.21 Account Takeover via SSO

@better-auth/sso versions before 1.6.21 contain multiple authentication bypass vulnerabilities in SSO provider handling that allow attackers to sign in as arbitrary users. Attackers can exploit domain verification parsing mismatches, orphaned provider accounts, unbound SAML assertions, or reflect...

CVE-2026-18217

A flaw was found in the SAML protocol implementation of Keycloak, an open-source identity and access management solution. The issue occurs when Keycloak handles SAML authentication requests using the HTTP-Redirect binding. If a client is configured with a wildcard redirect URL, an attacker can...

CVE-2026-18217

CVE-2026-18217 affects Keycloak’s SAML protocol implementation, specifically when handling SAML authentication requests via HTTP-Redirect binding with wildcard redirect URLs. The root cause is a query-string handling flaw that allows an attacker to craft a request whose parameters are preserved a...

SUSE CVE-2026-9090

Casdoor versions 2.362.0 and earlier contain a vulnerability that allows an attacker to bypass authentication by supplying an arbitrary signing certificate. The buildSpCertificateStore function extracts the X.509 certificate directly from the incoming SAMLResponse instead of using the trusted...

SUSE CVE-2026-9093

In Casdoor versions 2.362.0 and earlier, the SAML service provider implementation does not validate the AudienceRestriction element in SAML assertions. The buildSp function in object/samlsp.go never sets AudienceURI on the gosaml2 SAMLServiceProvider struct and never inspects...

SUSE CVE-2026-9096

Casdoor versions 2.362.0 and earlier do not enforce SAML assertion time bounds. The gosaml2 library reports all time-validation results, including NotOnOrAfter and NotBefore, in the assertionInfo.WarningInfo field. However, ParseSamlResponse never reads this field, meaning that time bounds are...
