From 150f6e9eb5f4fcab6111fa77e58ce0f82e05feaa Mon Sep 17 00:00:00 2001 From: arunSunnyKVS Date: Fri, 17 Jul 2026 10:57:31 +0000 Subject: [PATCH] feat: deployment-aware agentic risk amplification scoring Adds a per-evaluator risk score (0-10) that amplifies a finding's static severity by the target's agentic power, so the same flaw scores higher on an autonomous, tool-rich, multi-tenant agent than on a read-only chatbot. Replaces the cosmetic "Avg Score" column with "Risk (this agent)". - amplify.ts: pure amplifiedRisk(severity, isFinding, power) = base + (10-base)*power, with CVSS/AIVSS band floors. Worst-case per evaluator (findings only, else 0.0); averaging is deliberately avoided so one breach can't be hidden by sibling passes. - agentProfile.ts: deriveAgentProfile() heuristically infers the power profile from businessUseCase + target metadata already in the config -- no new setup questions. - aggregate.ts: buildUnifiedReport computes per-evaluator risk when a profile is present. The summary shape and severity-weighted headline scores are untouched. - report: new "Base Sev" + "Risk (this agent)" columns with a plain-English caption explaining why findings were amplified. - tests: unit coverage for amplify + agentProfile; existing equivalence/smoke pass. Follows the OWASP AIVSS amplification model, reduced to something fully automatic.
