CVE-2026-74909
NVD: Keycloak provides a policy enforcer to protect applications by matching incoming web requests against defined security policies. NVD: A flaw was found where the enforcer fails to correctly normalize web addresses that contain special encoded characters, such as those representing semicolons or directory traversal segments. NVD: An authenticated user can use these encoded characters to trick the enforcer into applying a less restrictive security policy than intended, potentially gaining unauthorized access to sensitive administrative or private application endpoints.
