Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Validates redirect target URLs in the session course edit page to block arbitrary external redirects and parameter leakage.

AC-4 Information Flow Enforcement good match
prevent

Enforces information flow rules that restrict redirects from the LMS edit function to only approved internal destinations.

SI-15 Information Output Filtering partial match
prevent

Filters outgoing redirect URLs and parameters generated after coach assignment saves to prevent exfiltration to attacker sites.
