{"id":"CVE-2023-45810","summary":"OpenFGA denial of service","details":"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.","aliases":["GHSA-hr4f-6jh8-f2vq","GO-2023-2121"],"modified":"2026-03-14T12:21:18.389646Z","published":"2023-10-17T22:29:00.293Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/45xxx/CVE-2023-45810.json","cwe_ids":["CWE-400"],"cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/45xxx/CVE-2023-45810.json"},{"type":"ADVISORY","url":"https://github.com/openfga/openfga/security/advisories/GHSA-hr4f-6jh8-f2vq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-45810"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openfga/openfga","events":[{"introduced":"0"},{"fixed":"9f60a57262bec4a5f45c1d24a3f0807872e29e28"}]}],"versions":["v0.1.0","v0.1.1","v0.1.2","v0.1.3","v0.1.4","v0.1.5","v0.1.6","v0.1.7","v0.2.0","v0.2.1","v0.2.2","v0.2.3","v0.2.4","v0.2.5","v0.3.0","v0.3.1","v0.3.2","v0.3.3","v0.3.4","v0.3.5","v0.3.6","v0.3.7","v0.4.0","v0.4.1","v0.4.2","v0.4.3","v1.0.0","v1.0.1","v1.1.0","v1.1.1","v1.2.0","v1.3.0","v1.3.1","v1.3.2","v1.3.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-45810.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
