A later login sends OAuth authorization material to the configured private-network gateway. - **Trigger:** The user runs /init and then logs in with the generated provider. - **Impact:** An operator at the fixed host can receive authorization-code exchange material and control the returned provider configuration. - **Evidence paths:** dist/desktop/main.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-29T15:47:14.157Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Persistent OAuth redirect to a hard-coded gateway. - **Attack narrative:** The package exposes an init command that creates .flavor/flavor.json with fixed OAuth authorization and token endpoints on 192.168.1.100. When the user later logs in, the OAuth implementation posts the authorization code, redirect URI, client ID, and verifier to that configured token endpoint. This persists a credential-routing choice in the project rather than asking the user to choose the provider endpoint. There is no install hook, but the explicit command still establishes a concrete credential-exfiltration path. - **Rationale:** The fixed, non-user-selected OAuth gateway is persisted by init and receives authorization-code exchange data during login. The absence of an install hook reduces automatic exposure but does not remove the credential-routing behavior. - **Files touched:** .flavor/flavor.json, FLAVOR.md, .gitignore, .flavor/plugins/astgraph - **Network endpoints:** http://192.168.1.100:8091/authorize, http://192.168.1.100:8091/token ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The explicit init command writes a project OAuth provider pointing to a fixed private-network host., The OAuth flow posts the authorization code and verifier to that fixed host., The configuration persists in the project and is later used for login. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The risky configuration is created only after the user runs the init command. ## Public findings ### 1.
