GHSA-794G-X443-36F7 Keycloak: Unauthorized access via improper validation of encrypted SAML assertions

Keycloak's SAML broker endpoint does not properly validate encrypted assertions when the overall SAML response is not signed. An attacker with a valid signed SAML assertion can exploit this by crafting a malicious SAML response, injecting an encrypted assertion for an arbitrary principal, leading...

Improper Neutralization of Data within XPath Expressions ('XPath Injection')

Overview Affected versions of this package are vulnerable to Improper Neutralization of Data within XPath Expressions 'XPath Injection' through the XPath Transform process. An attacker can cause the application to become unresponsive or crash by sending specially crafted messages that exploit thi...

SimpleSAMLphp has Possible DoS via XPath Transform

Summary This library turned out to be vulnerable to Denial-of-Service attacks using XPath transforms. A mitigation has been put in place to restrict the number of transforms and to restrict transforms to only the transform-algorithms mentioned in the SAML 2.0 Core Specifications and specifically...

GHSA-6929-8P9F-26JX SimpleSAMLphp HTTP-Artifact TLS validator confusion allows cross-IdP authentication bypass

Summary SimpleSAMLphp's HTTP-Artifact receive path can treat an unsigned embedded SAML Response as cryptographically valid for the wrong IdP. In the HTTPArtifact::receive flow, the SOAP ArtifactResponse receives a TLS-based validator from SOAPClient::addSSLValidator. The embedded SAML Response th...
