A later login directs authentication to that gateway and makes its provider the default for both agents. - **Trigger:** The user runs flavor init and subsequently starts the OAuth login flow. - **Impact:** A user may authenticate through an undisclosed gateway that can receive the OAuth authorization code and issue the token used for model requests. - **Evidence paths:** package.json, dist/cli-main.js, dist/chunk-S525EOFQ.js - **Review source:** ai\_review - **Reviewed:** 2026-08-29T09:40:06.426Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Persistent OAuth endpoint redirection through generated agent configuration. - **Rationale:** The fixed, undisclosed OAuth gateway and persistent default-agent configuration create a real credential-redirection risk. It is user-command triggered rather than install-time, so the source supports a warning rather than a publish block. - **Files touched:** .flavor/flavor.json, .flavor/sessions, .flavor/skills, .flavor/plugins, FLAVOR.md, .gitignore - **Network endpoints:** http://192.168.1.100:8091/authorize, http://192.168.1.100:8091/token ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** The explicit init command creates a project OAuth provider pointing to a fixed private-network host., That generated provider becomes the default for both main and subagents., The OAuth flow opens the configured authorization URL and posts the authorization code to the configured token URL. - **Evidence against:** The manifest has no preinstall, install, or postinstall hook., The configuration write occurs only after the user runs the explicit init command., The initializer leaves an existing .flavor/flavor.json unchanged. ## Public findings ### 1.
