Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Secure development lifecycle mandates validation of all external references to prevent uncontrolled resource access.
A.8.26 only requires that security requirements (including those that could address sphere separation) be identified and specified during development or acquisition; it does not itself enforce, implement or mandate any mechanism that stops external references from resolving outside the intended sphere, so the weakness remains exploitable.
A.8.27 mandates security-by-design principles (least privilege, default-deny, distrust-external-input, fail-securely, zero-trust verification) plus design reviews that can catch and stop many externally-controlled cross-sphere references before they reach production, but leaves a bounded remainder (e.g. runtime name resolution, configuration-driven references, or supplier code not covered by the contract) that can still be present and exploitable.
Secure coding standards require input validation and canonicalization to block externally controlled resource references.
Security testing can detect instances of the weakness but does not prevent it at design or coding time.
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-610, a class-level weakness, and none of its children carries one either.
