CVE-2023-45810
OpenFGA denial of service
In short
OpenFGA, an authorization engine, can become unresponsive when many ListObjects requests are made because the application fails to properly release memory and resources after responding to these requests. An attacker can send enough of these requests to make the service unavailable to legitimate users.
Technical detail
OpenFGA versions prior to 1.3.4 contain a resource exhaustion vulnerability (CWE-400) in the ListObjects operation where response handling does not properly deallocate memory and system resources. An unauthenticated remote attacker can trigger a denial of service by sending a high volume of ListObjects requests, causing cumulative resource consumption and eventual service unavailability.
Summary generated and translated by AI from the official description.
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.
