 ### 🐛 Bug fixes
 
+- [eas-cli] Escape Apple credentials before scrubbing them from `eas metadata` telemetry, so a value containing `+`, `.` or `(` is redacted instead of being sent verbatim or throwing. ([#4256](https://github.com/expo/eas-cli/pull/4256) by [@dennytosp](https://github.com/dennytosp))
