Prior to 8.0.3, cloneFeatureToggle and POST /api/admin/projects/:projectId/features/:featureName/clone authorize creation in the destination project but do not verify access to the source project. Because feature names are globally unique, a user with create or clone permission in one project who knows or guesses another project's feature name can copy that feature into the authorized project and inspect its strategy parameters, constraints, variants, and variant payloads. This issue is fixed in version 8.0.3.","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":5.3},"cvss_v3":null,"cwes":["CWE-639"],"references":["https://github.com/Unleash/unleash/commit/2dc6ac0e8ba524ec7a2e9bc96a0e01d9d6f5a35a","https://github.com/Unleash/unleash/releases/tag/v8.0.3","https://github.com/Unleash/unleash/security/advisories/GHSA-8xcj-9hfr-fh9j","https://github.com/Unleash/unleash/security/advisories/GHSA-8xcj-9hfr-fh9j"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-76910","score":0.00414,"percentile":0.35669,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-8xcj-9hfr-fh9j","url":"https://osv.dev/vulnerability/GHSA-8xcj-9hfr-fh9j","summary":"Unleash: Clone-feature lets a user copy a feature from a project they cannot read","modified":"2026-09-22T21:00:03.639342151Z","packages":[{"ecosystem":"npm","name":"unleash-server","purl":"pkg:npm/unleash-server","ranges":["<8.0.3"],"fixed":["8.0.3"]}]}],"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).
