From 7bef75d42f7f2e351a85ab7c3242a1c6a410e175 Mon Sep 17 00:00:00 2001 From: Chap Ambrose Date: Wed, 17 Jun 2026 17:11:06 +0000 Subject: [PATCH 1/2] feat: add Touch ID authentication for non-GET requests Add Touch ID biometric authentication for mutating HTTP requests on macOS. Provides enhanced security via native LocalAuthentication framework. Features: - Touch ID authentication for POST/PUT/PATCH/DELETE requests - GET/HEAD requests bypass authentication (read-only operations) - Native macOS authentication dialog with fingerprint icon - Platform detection with graceful fallback - Environment control via HEROKU_TOUCH_ID_ENABLED - Optional 'ht' command with Touch ID enabled by default Implementation: - Swift script for native LocalAuthentication framework - Init and prerun hooks wrap APIClient for request interception - Secure execFile usage (prevents command injection) - Comprehensive documentation and unit tests Usage: # Enable Touch ID for heroku command export HEROKU_TOUCH_ID_ENABLED=true heroku config:set KEY=value -a app-name # Or use ht command (Touch ID enabled by default) ht config:set KEY=value -a app-name Co-authored-by: Claude --- bin/ht | 41 +++++++ package.json | 11 +- scripts/touch-id-auth.swift | 42 +++++++ src/hooks/init/touch-id.ts | 61 +++++++++++ src/hooks/prerun/touch-id.ts | 9 ++ src/lib/biometric/README.md | 103 ++++++++++++++++++ src/lib/biometric/api-client-wrapper.ts | 70 ++++++++++++ src/lib/biometric/touch-id.ts | 97 +++++++++++++++++ test/unit/lib/biometric/touch-id.unit.test.ts | 60 ++++++++++ 9 files changed, 491 insertions(+), 3 deletions(-) create mode 100755 bin/ht create mode 100755 scripts/touch-id-auth.swift create mode 100644 src/hooks/init/touch-id.ts create mode 100644 src/hooks/prerun/touch-id.ts create mode 100644 src/lib/biometric/README.md create mode 100644 src/lib/biometric/api-client-wrapper.ts create mode 100644 src/lib/biometric/touch-id.ts create mode 100644 test/unit/lib/biometric/touch-id.unit.test.ts diff --git a/bin/ht b/bin/ht new file mode 100755 index 0000000000..6e248b362f --- /dev/null +++ b/bin/ht @@ -0,0 +1,41 @@ +#!/usr/bin/env -S node --no-deprecation + +// ht - Heroku CLI with Touch ID authentication +// This is an alternate entry point that enables Touch ID for non-GET requests + +// Enable Touch ID by default for this command +process.env.HEROKU_TOUCH_ID_ENABLED = 'true' + +import {execute, settings} from '@oclif/core' + +// Enable performance tracking when oclif:perf is specified in DEBUG +if (process.env.DEBUG?.includes('oclif:perf') || process.env.DEBUG === 'oclif:*' || process.env.DEBUG === '*') { + settings.performanceEnabled = true +} + +process.env.HEROKU_UPDATE_INSTRUCTIONS = process.env.HEROKU_UPDATE_INSTRUCTIONS || 'update with: "npm update -g heroku"' + +const now = new Date() +const cliStartTime = now.getTime() + +const {getTelemetryDisabledReason, isTelemetryEnabled, telemetryDebug} = await import('../dist/lib/analytics-telemetry/telemetry-utils.js') +const enableTelemetry = isTelemetryEnabled() + +if (enableTelemetry) { + telemetryDebug('Telemetry enabled: setting up handlers (beforeExit, SIGINT, SIGTERM)') + // Dynamically import telemetry modules + const {setupTelemetryHandlers} = await import('../dist/lib/analytics-telemetry/worker-client.js') + const {computeDuration} = await import('../dist/lib/analytics-telemetry/telemetry-utils.js') + + // Setup all telemetry handlers (beforeExit, SIGINT, SIGTERM) + setupTelemetryHandlers({ + cliStartTime, + computeDuration, + enableTelemetry, + }) +} else { + const reason = getTelemetryDisabledReason() + telemetryDebug('Telemetry disabled (%s): skipping telemetry handler setup', reason) +} + +await execute({dir: import.meta.url}) diff --git a/package.json b/package.json index 56e3613d48..651fe101ab 100644 --- a/package.json +++ b/package.json @@ -3,7 +3,10 @@ "description": "CLI to interact with Heroku", "version": "11.5.0", "author": "Heroku", - "bin": "./bin/run.js", + "bin": { + "heroku": "./bin/run.js", + "ht": "./bin/ht" + }, "bugs": "https://github.com/heroku/cli/issues", "dependencies": { "@heroku-cli/command": "12.4.2", @@ -183,13 +186,15 @@ "init": [ "./dist/hooks/init/version", "./dist/hooks/init/terms-of-service", - "./dist/hooks/init/setup-otel-telemetry" + "./dist/hooks/init/setup-otel-telemetry", + "./dist/hooks/init/touch-id" ], "postrun": [ "./dist/hooks/postrun/send-otel-telemetry" ], "prerun": [ - "./dist/hooks/prerun/collect-and-send-herokulytics" + "./dist/hooks/prerun/collect-and-send-herokulytics", + "./dist/hooks/prerun/touch-id" ], "preupdate": [ "./dist/hooks/preupdate/check-npm-auth" diff --git a/scripts/touch-id-auth.swift b/scripts/touch-id-auth.swift new file mode 100755 index 0000000000..8bb7334fe7 --- /dev/null +++ b/scripts/touch-id-auth.swift @@ -0,0 +1,42 @@ +#!/usr/bin/env swift + +import Foundation +import LocalAuthentication + +let context = LAContext() +var error: NSError? + +// Check if biometric authentication is available +guard context.canEvaluatePolicy(.deviceOwnerAuthenticationWithBiometrics, error: &error) else { + if let error = error { + print("UNAVAILABLE:\(error.localizedDescription)") + } else { + print("UNAVAILABLE:Touch ID not available") + } + exit(1) +} + +// Get the reason from command line arguments +let reason = CommandLine.arguments.count > 1 ?
