syncfusion-angular-uploader

No clear malware observed; the example demonstrates chunked file upload mechanics but contains several security shortcomings that make it unsafe for production as-is: unvalidated client-supplied filenames, predictable temporary filenames and collision/race risks, reliance on client-controlled ContentType, no validation of numeric form inputs, and no authentication/authorization or quota checks. Recommended mitigations: canonicalize and validate filenames (reject path separators, restrict characters, or use a server-generated safe filename), use a unique per-upload temporary token (GUID or user-scoped ID) for temp files, enforce authentication/authorization and per-user storage isolation, validate and bound numeric form fields, enforce max file size and quotas, and use atomic operations and proper error handling when finalizing files.
