A user with _create_ permissions in one project can clone a feature from another project they cannot read and then inspect the copied configuration.\n\nThis vulnerability cannot be confirmed without Enterprise access. Report is based on a circumstantial evidence in the open-source repository.\n\n### Details\n`src/lib/features/feature-toggle/feature-toggle-service.ts` implements `cloneFeatureToggle`. This operation needs authorization for both sides: permission to read/copy the source feature and permission to create the destination feature.\n\nThe clone path validates permissions against the destination project, but not against the source project that owns `featureName`. Because feature names are globally unique, a caller can reference a feature outside projects they can access.\n\n### PoC\n1. Create or identify two projects: `P1` with a private or restricted feature named `secret-feature`, and `P2` where the attacker has clone/create permissions.\n2. Authenticate as the attacker.\n3. Send:\n\n```http\nPOST /api/admin/projects/P2/features/secret-feature/clone\nContent-Type: application/json\n\n{ \"name\": \"secret-feature-copy\" }\n```\n\n4. Open `P2` and inspect `secret-feature-copy`. Verify if strategy parameters, constraints, variants, and variant payloads from the source feature have been copied.\n\n### Impact\nUsers with permissions on one project can disclose feature configuration from another project if they know or guess the source feature name. Feature names could be available in more public applications that have a common SDK access to multiple projects.","state":0,"publishedAt":"2026-09-22T20:34:40+00:00","modifiedAt":"2026-09-22T21:00:03.6393422+00:00","affected":[{"ecosystem":"npm","name":"unleash-server","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"8.0.3"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/Unleash/unleash/security/advisories/GHSA-8xcj-9hfr-fh9j","https://github.com/Unleash/unleash/commit/2dc6ac0e8ba524ec7a2e9bc96a0e01d9d6f5a35a","https://github.com/Unleash/unleash","https://github.com/Unleash/unleash/releases/tag/v8.0.3"],"sourceUrl":"https://github.com/advisories/GHSA-8xcj-9hfr-fh9j","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-8xcj-9hfr-fh9j","identifiers":["GHSA-8xcj-9hfr-fh9j","CVE-2026-76910"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
