Potential fixes for 2 code scanning alerts

[jf205]

Potential fixes for 2 code scanning alerts from the A large campaign test security campaign:

• https://github.com/dsp-testing/android-patterns/security/code-scanning/1
  To fix the problem, we need to ensure that the escape sequence \b is correctly interpreted as a word boundary in the regular expression. This can be achieved by either using a regular expression literal or by adding an extra backslash to escape the backslash in the string literal.

  The best way to fix this without changing existing functionality is to add an extra backslash in the string literal. This ensures that the \b is correctly interpreted as a word boundary in the regular expression.

  To fix the problem, we need to verify the origin of the incoming messages in the postMessage handler. This involves checking the origin property of the event object against a list of trusted origins. If the origin is not trusted, the message should be ignored.

  1. Identify the trusted origins for the application.
  2. Modify the postMessage handler to include a check for the origin.
  3. Only process the message if the origin is trusted.

Suggested fixes powered by Copilot Autofix. Review carefully before merging.
