What an attacker can do

Unauthenticated attackers can send a decoy filename with filename*=iso-8859-1''shell.php, or filename* alone, so FILES-based rules never see the real name, letting dangerous uploads reach backends that honor filename*. Vendor/CNA’s CVSS 4.0 assessment (base score 6.3/10) rates confidentiality and availability impact as none; integrity impact as low.
