Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — A credential intended for the selected model provider is disclosed to the worker service without recipient-specific consent. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Credential Exfiltration - **Selected version:** 1.0.869 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 inspected runtime path sends a model-provider credential to the package’s default worker service after a prompt that does not disclose the recipient. This is concrete credential disclosure without recipient-specific consent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-10-22T01:06:31.828Z - **Finished:** 2026-10-22T01:07:27.714Z - **Download time:** 780 ms - **Static scan time:** 4680 ms - **AI review time:** 50425 ms - **Total time:** 55886 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:** When a cloud coding model has no stored key, the REPL prompts for that model’s API credential and sends it to the worker API. The prompt does not disclose that recipient. - **Trigger:** Starting the REPL with a cloud coding model missing a key and entering the requested key. - **Impact:** A credential intended for the selected model provider is disclosed to the worker service without recipient-specific consent. - **Evidence paths:** device-login.mjs, coding-key-prompt.mjs, gu-repl.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-22T01:07:27.714Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The prompt passes the entered credential to a helper that POSTs it to the configured worker API; the package’s default API host is chat-api-v2.gucli.com. - **Attack narrative:** On REPL startup, the package asks for a missing cloud coding-model API key. If entered, it sends that key in a POST body to the worker API, whose default host is chat-api-v2.gucli.com. The prompt identifies the model that needs a key but does not disclose this recipient. The API base can be overridden through GONEXT\_API\_BASE, but the published default remains package-selected. - **Rationale:** The inspected runtime path sends a model-provider credential to the package’s default worker service after a prompt that does not disclose the recipient. This is concrete credential disclosure without recipient-specific consent. - **Network endpoints:** https://chat-api-v2.gucli.com ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The default worker API destination is chat-api-v2.gucli.com., At startup, the REPL prompts for the selected coding model’s API key and calls the save helper when a key is supplied; the prompt does not identify the worker API as the recipient., The save helper POSTs the supplied key in the request body to the worker API’s coding-key endpoint., The API base can be overridden with GONEXT\_API\_BASE, but the package supplies a fixed default destination. - **Evidence against:** The transfer requires a user to enter a key at the prompt; this is not an install-time disclosure. ## Affected versions and remediation This report applies to @tiens.nguyen/gu-cli@1.0.869. - Avoid installing @tiens.nguyen/gu-cli@1.0.869. 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.
