In versions prior to 1.13.1, under specific conditions, models using conditions with caching enabled can result in two different check requests producing the same cache key. This can result in OpenFGA reusing an earlier cached result for a different request. Users are affected if the model has relations which rely on condition evaluation andncaching is enabled. OpenFGA v1.13.1 contains a patch.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H","score":5.8},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-20","CWE-345","CWE-1289"],"references":["https://github.com/openfga/openfga/commit/049b50ccd2cc7e163bd897f3d17a7b859ad146f8","https://github.com/openfga/openfga/releases/tag/v1.13.1","https://github.com/openfga/openfga/security/advisories/GHSA-h6c8-cww8-35hf"],"products":["openfga:openfga"],"source":"nvd","synced_at":"2026-10-19T22:28:18.033120106+00:00"},"epss":{"cve":"CVE-2026-33729","score":0.0025,"percentile":0.1645,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-h6c8-cww8-35hf","url":"https://osv.dev/vulnerability/GHSA-h6c8-cww8-35hf","summary":"OpenFGA has an Authorization Bypass through cached keys","modified":"2026-09-10T03:50:39.441218890Z","packages":[{"ecosystem":"Go","name":"github.com/openfga/openfga","purl":"pkg:golang/github.com/openfga/openfga","ranges":["<1.13.1"],"fixed":["1.13.1"]}]},{"id":"GO-2026-4857","url":"https://osv.dev/vulnerability/GO-2026-4857","summary":"OpenFGA has an Authorization Bypass through cached keys in github.com/openfga/openfga","modified":"2026-03-27T17:14:39.611226Z","packages":[{"ecosystem":"Go","name":"github.com/openfga/openfga","purl":"pkg:golang/github.com/openfga/openfga","ranges":["<1.13.1"],"fixed":["1.13.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
