Prior to 1.18.1, the ListUsers API could return a user that should have been excluded when an authorization relation used an intersection containing a base but not excluded operand, the base was granted through a type-bound public wildcard, and the excluded user also had a concrete tuple through another intersection operand. In pkg/server/commands/listusers/list_users_rpc.go, expandIntersection counted the concrete tuple and wildcard without first rejecting entries in excludedUsersMap. Applications that used ListUsers to enumerate or enforce access could therefore treat an excluded user as authorized. This issue is fixed in version 1.18.1.","state":0,"publishedAt":"2026-09-16T15:17:39.66+00:00","modifiedAt":"2026-09-24T21:25:27.05+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","score":5.3,"severity":"MEDIUM"}],"references":["https://github.com/openfga/openfga/commit/171806c93b86bca29e0212ceb8b6ee9c48eb9ac3","https://github.com/openfga/openfga/releases/tag/v1.18.1","https://github.com/openfga/openfga/security/advisories/GHSA-g3pg-frfm-pr2m"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-61709","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-281","CWE-863"],"productCriteria":[],"sourceDates":{"published":"2026-09-16T15:17:39.660","lastModified":"2026-09-24T21:25:27.050"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
