Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The flow client forwards a locally stored third-party AI-provider credential to the Yujin worker. This is a concrete credential-exfiltration path to a non-provider service. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-11T13:04:54.565Z - **Finished:** 2026-09-11T13:06:11.679Z - **Download time:** 1012 ms - **Static scan time:** 7864 ms - **AI review time:** 68237 ms - **Total time:** 77114 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The flow client forwards a locally stored third-party AI-provider credential to the Yujin worker. This is a concrete credential-exfiltration path to a non-provider service. - **Trigger:** A runtime feature invokes the HITO flow client after a BYOK provider is configured. - **Impact:** The Yujin worker can receive and use the user's AI-provider credential. - **Evidence paths:** dist/license/hito4\_client.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T13:06:11.679Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Reads a vault API key and places it in an outbound HTTP header. - **Attack narrative:** When a HITO flow runs, the package resolves the selected provider's local API key, constructs a request to the Yujin worker, and sends the key as x-yf-brain-key. The destination is not the AI provider whose credential is being sent. No installation hook is involved, but this runtime credential forwarding exposes reusable third-party credentials to the package operator's service. - **Rationale:** The source directly transmits BYOK credentials to a fixed non-provider endpoint. The absence of install hooks limits the trigger but does not remove the credential-exfiltration behavior. - **Files touched:** ~/.yujin-forge/provider\_keys.json, vault slot byok\_\\_api\_key - **Network endpoints:** yujin-hito4.yujinapp.workers.dev ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The runtime reads a selected BYOK provider key from the local vault., It sends that key in an x-yf-brain-key request header to the fixed Yujin worker endpoint., The package exposes this networked client through its CLI and chat functionality. - **Evidence against:** package.json has no install, preinstall, or postinstall hook., The observed credential transfer occurs in a runtime flow client, not during package installation. ## Affected versions and remediation This report applies to @nac3/forge-cli@1.3.6. - Avoid installing @nac3/forge-cli@1.3.6. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
