Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 27 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Credential Exfiltration - **Selected version:** 1.3.19 - **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The package does not show malicious installation behavior, covert network exfiltration, or reviewer manipulation. However, automatic persistence of API and OAuth credentials during ordinary runtime use is a material security weakness that warrants a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-08-30T02:14:04.243Z - **Finished:** 2026-08-30T02:15:19.626Z - **Download time:** 507 ms - **Static scan time:** 12758 ms - **AI review time:** 62116 ms - **Total time:** 75383 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:** Running the CLI or desktop runtime can persist API and OAuth environment values to the user's Flavor configuration directory. No automatic install-time execution or external credential transmission was found. - **Trigger:** Run Flavor in a process that has one of the listed provider or OAuth environment values. - **Impact:** Credentials can remain on disk after the invoking process exits, increasing local disclosure risk. - **Evidence paths:** dist/chunk-HJOCNKPN.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-30T02:15:19.626Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic persistence of environment credentials during configuration loading. - **Rationale:** The package does not show malicious installation behavior, covert network exfiltration, or reviewer manipulation. However, automatic persistence of API and OAuth credentials during ordinary runtime use is a material security weakness that warrants a warning. - **Files touched:** ~/.flavor-code/.env, ~/.flavor-code/flavor.json, .env, .flavor/flavor.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Low - **Evidence for warning:** Runtime configuration automatically copies configured OpenAI, Anthropic, and OAuth environment values into a persistent home-directory .env file., The write occurs during normal configuration loading, without a dedicated export or confirmation action. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., Project initialization and self-update are explicit CLI subcommands., No source evidence shows credentials sent to an attacker-controlled endpoint or a hidden remote payload. ## Affected versions and remediation This report applies to flavor-code@1.3.19. - Review the evidence and your use of flavor-code@1.3.19 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
