Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly enforces validation of URLs and client headers to block crafted open-redirect inputs exploited by CVE-2026-48895.

AC-4 Information Flow Enforcement good match
prevent

Enforces information flow rules that can restrict untrusted redirects and header-driven destination changes used in this APISIX flaw.

SC-7 Boundary Protection partial match
prevent

Boundary protection mechanisms can filter or block malicious redirects at ingress points before session tokens are exposed.
