Description TEJ RATHI 2023-12-11 08:34:32 UTC 
Keycloak allows arbitrary URLs as SAML Assertion Consumer Service POST Binding URL (ACS), including JavaScript URIs (javascript:). Allowing JavaScript URIs in combination with HTML forms leads to JavaScript evaluation in the context of the embedding origin on form submission. Thus, Keycloak is vulnerable to Cross-Site Scripting (XXS) by registering a JavaScript URI as Assertion Consumer Service POST Binding URL.
