Vearch 3.5.2 through 3.5.9 contains an incorrect authorization vulnerability in Role.HasPermissionForResources that ignores stored ReadOnly or None privilege levels for resources listed in a role. Authenticated non-root users can upsert and delete documents with read-only access, or call PUT /roles to grant their role WriteRead privileges, escalating toward cluster administrator access.
