Incorrect Behavior Order: Authorization Before Parsing and Canonicalization

Overview org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services. Affected versions of this package are vulnerable to Incorrect Behavior Order: Authorization Before Parsing and Canonicalization due to the Authorization header...

EUVD-2026-1461

A flaw was found in Keycloak. The Keycloak Authorization header parser is overly permissive regarding the formatting of the "Bearer" authentication scheme. It accepts non-standard characters such as tabs as separators and tolerates case variations that deviate from RFC 6750 specifications...

Authentication Bypass

ruby-saml is vulnerable to authentication bypass. The vulnerability is due to improper handling of libxml2 canonicalization in Nokogiri when processing invalid XML, which returns an empty string used for DigestValue calculation, allowing an attacker to perform a Signature Wrapping attack and bypa...

Authentication Bypass

robrichards/xmlseclibs is vulnerable to authentication bypass. The vulnerability is due to improper handling in the libxml2 canonicalization process where invalid XML inputs may return an empty string, which allows an attacker to bypass authentication by manipulating the DigestValue computation...
