Can you link to a source that confirms this information can be collected with JavaScript (with browser comparison, ideally)? That seems outrageous if it was actually possible.
JavaScript is already sandboxed. You can only execute functions where there is an actual API defined by the browser to do so, for example
Date.getTime()
. There is / should be no way to get, say, your device ID. (With the exception of unpatched exploits that allow executing arbitrary code. But keep in mind browsers are likely one of the if not the most security tested software.)What you linked to here appears to specific to Google Tag Manager in a way that I don't fully understand, but is not related to how websites usually execute JavaScript code.
thank you for the clarification
