🎯 **What:** The vulnerability fixed was a potential Command Injection in PlatformShellService due to unescaped arguments passed to `Process.Start()` when handling `open` or `xdg-open` commands on OSX and Linux respectively.
⚠️ **Risk:** If a malicious path containing shell metacharacters or flags was passed to these methods, it could lead to arbitrary command execution with the privileges of the application.
🛡️ **Solution:** Used `ProcessStartInfo` with `UseShellExecute = false` and `ArgumentList` to safely pass the path argument without shell expansion. Additionally, prepended `./` to paths starting with `-` to prevent argument injection flags.

🎯 **What:** The vulnerability fixed was a potential Command Injection in PlatformShellService due to unescaped arguments passed to `Process.Start()` when handling `open` or `xdg-open` commands on OSX and Linux respectively.
⚠️ **Risk:** If a malicious path containing shell metacharacters or flags was passed to these methods, it could lead to arbitrary command execution with the privileges of the application.
🛡️ **Solution:** Used `ProcessStartInfo` with `UseShellExecute = false` and `ArgumentList` to safely pass the path argument without shell expansion. Additionally, prepended `./` to paths starting with `-` to prevent argument injection flags.
