CM-6 Configuration Settings partial match

Secure configuration settings can disable external entity processing in XML parsers.

SA-11 Developer Testing and Evaluation partial match

Developer testing can discover XXE flaws through targeted XML parsing tests.

SI-10 Information Input Validation partial match

Input validation can reject or sanitize XML containing external entity references.
