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.

AT-2 Literacy Training and Awareness
addresses: CWE-352

Awareness training educates users on avoiding untrusted links and actions that can be exploited via CSRF.

IA-11 Re-authentication
addresses: CWE-352

Requiring user re-entry of credentials for sensitive actions prevents automated forgery of requests without active user participation.

PM-14 Testing, Training, and Monitoring
addresses: CWE-352

Security testing regimens explicitly include checks for missing or ineffective anti-CSRF protections in web applications.

SI-4 System Monitoring
addresses: CWE-352

Detects anomalous request patterns consistent with cross-site request forgery.
