ضوابط أمان رفع الملفات وفحص الترويسة الثنائية

Supported resume formats (.PDF, .DOCX, .TXT), 4 MB size limit, magic-byte header verification, and prompt-injection stripping.

1. Strict 4 MB Limit & Magic-Byte Verification

Jobrov's UploadFileScanner inspects the binary header of every uploaded file (verifying %PDF for PDFs and PK for DOCX archives), enforces a 4 MB cap, and strips embedded scripts or prompt-injection sequences.
