Mitigating Controls (NIST 800-53 r5) AI

Information flow enforcement can restrict which destinations the server is allowed to contact on behalf of users.

Boundary protection limits the network reach of server-initiated requests even if SSRF occurs.

Input validation directly stops untrusted URLs from being accepted and fetched without destination checks.

removes
blocks

A.5.15 only requires defining and documenting an access control policy plus requirements; it does not itself enforce rules or stop a confused-deputy proxy from being introduced or exploited.

blocks

A.5.16 governs identity lifecycle, uniqueness, accountability and timely removal to support proper access rights assignment; it has no bearing on preserving original request sources or stopping confused-deputy proxying when a product forwards an upstream request.

degrades

Explicit access-rights assignment can restrict the product’s ability to act as an unintended proxy for external actors.

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-441, a class-level weakness, and none of its children carries one either.
