But if using `LookupResources` to find a list of banned resources instead, then some users that shouldn't have access may.\n\nGenerally, `LookupResources` is not and should not be used to gate access in this way - that's what the `Check` API is for. Additionally, version 1.22.0 has included a warning about this bug since its initial release.\n\n### Workarounds\nAvoid using `LookupResources` for negative authorization decisions if using `1.22.0`. \n\n### Patches\nThe only affected release is [v1.22.0](https://github.com/authzed/spicedb/releases/tag/v1.22.0), and it is patched in [v1.22.2](https://github.com/authzed/spicedb/releases/tag/v1.22.2) (there is no v1.22.1 release, though there is a git tag).\n\n### References\n- https://github.com/authzed/spicedb/pull/1397\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Open an issue in [SpiceDB](https://github.com/authzed/spicedb)\n* Ask a question in the [SpiceDB Discord](https://authzed.com/discord)\n","published":"2023-06-26T19:32:59.829Z","modified":"2026-10-28T02:30:58.222793187Z","cvss":{"score":3.7,"severity":"LOW","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N"},"epss":{"score":0.00448,"percentile":0.36833,"asOf":"2026-08-08"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/authzed/spicedb","fixedVersion":"1.22.2"}],"fix":{"url":"https://github.com/authzed/spicedb/pull/1397","label":"authzed/spicedb#1397"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/35xxx/CVE-2023-35930.json"},{"type":"ADVISORY","url":"https://github.com/authzed/spicedb/security/advisories/GHSA-m54h-5x5f-5m6r"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-35930"},{"type":"FIX","url":"https://github.com/authzed/spicedb/pull/1397"},{"type":"PACKAGE","url":"https://github.com/authzed/spicedb"},{"type":"WEB","url":"https://github.com/authzed/spicedb/releases/tag/v1.22.2"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:58.222793187Z"}}
