CVE-2026-76910

5.3 MEDIUM 0.4% exploit odds Fix listed Auth & access

What it is

Unleash is an open-source feature management platform. 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.
