Priority Score
Attack Technique
Server-Side Request Forgery exploits applications that fetch remote resources based on user-supplied URLs.
XML External Entity (XXE) attacks exploit XML parsers that process Document Type Definitions (DTDs) without proper restrictions.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
