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 package-generated default directs OAuth login exchange material to a fixed private-network recipient unrelated to the configured Anthropic provider. User invocation controls when the flow runs, but does not establish consent to send the exchange material to that recipient. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-21T06:48:25.546Z - **Finished:** 2026-10-21T06:51:48.970Z - **Download time:** 1040 ms - **Static scan time:** 10685 ms - **AI review time:** 191698 ms - **Total time:** 203424 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 generated default OAuth configuration sends login exchange material to a fixed private-network host selected by the package. This creates a credential disclosure path during login. - **Trigger:** A user initializes a project and then starts OAuth login using the generated provider configuration. - **Impact:** The fixed recipient can receive OAuth exchange material for the account being authenticated. - **Evidence paths:** package.json, dist/cli.js, dist/desktop/main.js - **Review source:** ai\_review - **Reviewed:** 2026-10-21T06:51:48.970Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The login flow builds authorization against the configured host, receives an authorization code, and posts the code and verifier to the configured token endpoint. - **Attack narrative:** The CLI initialization path writes a default provider whose OAuth authorization and token endpoints use a fixed private-network host. When the user later logs in with that configuration, the package sends the returned authorization code and verifier to that host. The source does not establish recipient-specific consent for sending login material there. - **Rationale:** The package-generated default directs OAuth login exchange material to a fixed private-network recipient unrelated to the configured Anthropic provider. User invocation controls when the flow runs, but does not establish consent to send the exchange material to that recipient. - **Files touched:** dist/desktop/main.js - **Network endpoints:** http://192.168.1.100:8091/authorize, http://192.168.1.100:8091/token ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package exposes a CLI initialization command and a desktop main entrypoint., Initialization writes a default OAuth provider that directs authorization and token exchange to a fixed private-network host., The login flow uses the configured provider and constructs an authorization URL for that host., The flow sends the returned authorization code and verifier to the configured token URL., The vendor parser uses generated embedded assembly code in its runtime; that separate eval match does not account for the OAuth behavior. - **Evidence against:** The default configuration is created when the user invokes initialization, and the exchange requires a subsequent login flow. ## Affected versions and remediation This report applies to flavor-code@1.3.4. - Avoid installing flavor-code@1.3.4. 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.
