PR.PS-06 full match
prevents

Secure SDLC practices directly prevent introduction of improper recursive entity handling in XML code.

PR.PS-01 mostly match
prevents

Hardened configuration baselines can disable or limit DTD entity expansion in XML parsers.

ID.RA-01 partial match
prevents

Identifying and recording vulnerabilities can discover XML entity expansion flaws before exploitation.

finds

Security testing can detect and block XML entity-expansion vulnerabilities before deployment.

prevents

Secure SDLC mandates input validation and parser hardening that can prevent unbounded entity expansion.

prevents

Application security requirements can explicitly call for limits on XML entity recursion and DTD processing.

prevents

Secure architecture principles discourage unsafe parser configurations that enable entity expansion attacks.

prevents

Secure coding standards directly require disabling or restricting recursive entity references in XML parsers.
