Cross-site scripting via unvalidated SAML ACS URLs
Published Apr 25, 2024 · Updated Sep 11, 2026
Cross-site scripting in Keycloak before 22.0.10 and 24.0.0 through 24.0.2 allows remote authenticated users to execute JavaScript via SAML. SAML client registration accepts a javascript: URI as an Assertion Consumer Service POST Binding URL and embeds it in an HTML form action. A realm administrator or client with registration access must save the URI, and a targeted user must submit the form before script runs in the embedding origin.
