The application specifies a **deprecated minimum iOS version** in its `MinimumOSVersion` property within the `Info.plist` file. Supporting outdated iOS versions can expose the application and its users to security vulnerabilities that have been addressed in newer iOS releases.

Older iOS versions may contain:
- Known security vulnerabilities that have been patched in newer versions
- Deprecated APIs that may not follow current security best practices
- Missing security features and protections introduced in recent iOS versions
- Potential compatibility issues with modern security frameworks

Applications that support very old iOS versions may be forced to use outdated security practices or may be unable to take advantage of the latest security enhancements provided by Apple. This creates a larger attack surface and potentially exposes users to security risks.

The minimum supported iOS version should be regularly reviewed and updated to balance user accessibility with security requirements.
