+# Frontend: WalletConnect/Google client IDs hardcoded as Dockerfile ARG defaults
+
+**Severity:** low
+**Domain:** Security
+**Labels:** frontend, configuration, ci-cd
+
+## Description
+
+`frontend/Dockerfile:14` has hardcoded default values for `NEXT_PUBLIC_WALLETCONNECT_PROJECT_ID` and `NEXT_PUBLIC_GOOGLE_CLIENT_ID` in `ARG` defaults. Forks or copies of this repo will silently use production IDs without being aware.
+
+## Options
+
+1. Remove defaults; require build-args/CI to supply them.
+2. Keep defaults since values are public-by-design but document them.
+3. Move to runtime env only.
+
+## Recommendation
+
+Remove the baked defaults and supply via CI build-args to avoid forks reusing prod IDs. These values are public but should be explicit.
