A flaw was found in the SAML protocol implementation of Keycloak, an open-source identity and access management solution. The issue occurs when Keycloak handles SAML authentication requests using the HTTP-Redirect binding. If a client is configured with a wildcard redirect URL, an attacker can craft a request that includes malicious parameters. When a user authenticates, Keycloak appends its legitimate response to the attacker's parameters. This can cause some service providers to process the attacker's data instead of the real login information, potentially leading to a user being logged into the wrong account.
Review the upstream advisory, identify the affected product in your inventory, and apply the vendor update when one is available.
Keycloak-services: keycloak-services: saml http-redirect binding response preserves query string leading to parameter pollution is listed in the HOL Guard supply-chain feed, but affected software is not mapped to a package. Review the upstream advisory for the affected product and vendor guidance. A flaw was found in the SAML protocol implementation of Keycloak, an open-source identity and access management solution.
