Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

PL-6 Security-related Activity Planning
addresses: CWE-799

The control requires defining frequency, timing, and approval for security interactions, directly addressing uncontrolled interaction rates.

SC-6 Resource Availability
addresses: CWE-799

Allocation policies inherently restrict interaction frequency, reducing the impact of excessive requests.

SI-8 Spam Protection
addresses: CWE-799

Spam protection explicitly controls interaction frequency by detecting and acting on bulk unsolicited messages from external sources.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

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.

A.8.26 Application security requirements partial match
blocks

Application security requirements explicitly include controls on interaction frequency and throttling.

A.8.27 Secure system architecture and engineering principles partial match
blocks

Secure architecture principles recommend rate-limiting and resource-management mechanisms.

A.8.28 Secure coding partial match
prevents

Secure coding practices can embed input-frequency and throttling checks in code.

A.8.6 Capacity management partial match
degrades

Capacity management directly limits request rates and resource exhaustion that CWE-799 describes.

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-799, a class-level weakness. Rules are authored against its narrower children: CWE-307.
