Medium [CVE-2026-9793] security policy bypass in jwe-encrypted request object processing
CVE-2026-9793Source published Source updated
A flaw was found in Keycloak. When a JSON Web Encryption (JWE) encrypted request object is submitted, Keycloak may incorrectly process unsigned claims if the decrypted content is raw JSON, bypassing the configured signature policy. This allows a remote attacker to submit unauthorized claims, leading to a compromise of data integrity within the OpenID Connect (OIDC) authorization flow. While a redirect URI allowlist acts as a compensating control, this vulnerability violates OIDC Core and Financial-grade API (FAPI) signing requirements. Affected products named by the advisory: Red Hat build of Keycloak 26.4; Red Hat build of Keycloak 26.6.
