Medium [CVE-2026-9705] Attacker can re-enable and take over disabled clients via Registration Access Token
CVE-2026-9705Source published Source updated
A flaw was found in Keycloak's client registration service. A remote attacker, possessing a previously issued Registration Access Token (RAT), could exploit this vulnerability to re-enable a client that an administrator had explicitly disabled. This bypasses security controls, allowing the attacker to reset the client's secret and potentially regain privileged API access. The primary impact includes unauthorized information disclosure and potential integrity compromise. This allows the attacker to bypass the administrator's explicit intent to disable the client, reset its secret, and restore OAuth client_credentials capability, potentially leading to unauthorized access to resources. Red Hat severity: Moderate — CVSS 6.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N). Weakness: CWE-613.…

Configure network firewalls to allow connections only from trusted hosts or networks that legitimately require access to this functionality. This limits the exposure of the vulnerable endpoint to unauthorized access attempts.
