# CVE-2026-97367: Keycloak-services: keycloak-services: dcr azp and sid claim substitution allows account rest session takeover

Status: published. Published: 2026-11-06. Updated: 2026-11-06.

A flaw was found in the Keycloak Account REST API where it incorrectly handles session identification. A malicious client owner can manipulate their own security tokens to point to a different user's active session. This allows the attacker to access and modify the victim's account information, potentially leading to a full account takeover by changing the recovery email and resetting the password.
