Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Enforces access authorizations so externally supplied references cannot reach resources outside the intended sphere.

AC-4 Information Flow Enforcement good match

Controls information flow between security domains, blocking resolution of external references to unintended spheres.

SI-10 Information Input Validation good match

Input validation directly rejects or sanitizes untrusted path strings before they reach filesystem operations.

AC-6 Least Privilege partial match

Least-privilege limits the set of files or directories any subject can affect, shrinking the blast radius of a path-control flaw.

SC-7 Boundary Protection partial match

Monitors and controls boundary communications, limiting the ability of external references to reach protected resources.

Least-privilege file authorization directly limits damage from externally controlled paths.

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.
