Denial of Service Vulnerability in OpenFGA

CVE-2023-45810 · HIGH Severity

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

OpenFGA is a flexible authorization/permission engine built for developers and inspired by Google Zanzibar. Affected versions of OpenFGA are vulnerable to a denial of service attack. When a number of `ListObjects` calls are executed, in some scenarios, those calls are not releasing resources even after a response has been sent, and given a sufficient call volume the service as a whole becomes unresponsive. This issue has been addressed in version 1.3.4 and the upgrade is considered backwards compatible. There are no known workarounds for this vulnerability.
