Signature wrapping vulnerability in Spring Security

  • Disclosed: 05.06.2020
  • Updated: 11.10.2026 11:21

Spring Security versions 5.2.x prior to 5.2.4 and 5.3.x prior to 5.3.2 contain a signature wrapping vulnerability during SAML response validation. When using the spring-security-saml2-service-provider component, a malicious user can carefully modify an otherwise valid SAML response and append an arbitrary assertion that Spring Security will accept as valid.
