XXE (XML External Entity Injection) Payload Structure: The input uses an XML DOCTYPE declaration to define an external entity (trustme) that references a local file (file:///etc/passwd). This is a classic XXE attack pattern. Exploitation Mechanism: When an XML parser processes this payload, it fetches the specified file (e.g., /etc/passwd on Unix systems) and embeds its content in the response. XXE allows attackers to read local files, execute remote requests, or perform server-side XML processing attacks. Relevance to Payload: The use of !ENTITY and SYSTEM directives within a DOCTYPE block is definitive of XXE exploitation.

XML External Entity attack is that can occur when a misconfigured XML parser allows applications to parse XML input from an unreliable source.
