I was prototyping flask applications on my macpro and today I noticed unusual logs. GET calls I didn't make. I am running the simple flask app on localhost with port 80.<p>The weird thing is each time I launch Chrome or Firefox and surf the web, the GET calls show up in my flask logs. I disabled all the extensions and they still show up. I wrote another simple flask app running on port 80 and its still the case.<p>Here are the standard output..<p><pre><code> * Serving Flask app "test" (lazy loading)
* Environment: production

Update: After eliminating all candidates - browser extensions, vscode, npm packages, I finally disconnected my pihole power supply and these GET calls stopped. The macpro is not using the pihole, is it possible the pihole is compromised is calling all ip ranges with port 80 ? I configured my flask app to run on port 0.0.0.0
