Unleash is an open-source feature management platform. Prior to 8.0.3, the Unleash admin API contains five authorization vulnerabilities. POST /api/admin/segments/strategies assigns the Promise returned by hasPermission without awaiting it, allowing authenticated users to modify segment assignments without UPDATE_FEATURE_STRATEGY permission for the target project and environment. GET /api/admin/projects/:projectId/features/:featureName/environments/:environment/variants does not bind the requested feature to projectId, allowing cross-project variant configuration disclosure. GET .../strategies/:strategyId uses strategyId without validating the project and feature context, allowing cross-project strategy configuration disclosure. getEnvironmentInfo does not validate that the requested feature belongs to the supplied project, allowing cross-project environment information disclosure. PUT /:projectId/tags accepts feature identifiers without verifying that they belong to the URL project, allowing cross-project tag modification. This issue is fixed in version 8.0.3.
