From 99205206bac2b8a07e359c84aa801cd0caeb9175 Mon Sep 17 00:00:00 2001 From: Landon Cox Date: Sun, 29 Mar 2026 08:27:54 -0700 Subject: [PATCH 1/6] fix: always derive GH_HOST from GITHUB_SERVER_URL to prevent proxy leakage When --env-all passes through a proxy-rewritten GH_HOST (e.g. localhost:18443 from DIFC proxy), gh CLI fails with "none of the git remotes correspond to GH_HOST". Fix by always deriving GH_HOST from GITHUB_SERVER_URL (the canonical source injected by the Actions runner) instead of preserving leaked proxy values. For GHES/GHEC: overrides any leaked value with the correct hostname. For github.com: deletes any leaked GH_HOST so gh CLI uses its default.
