Practical Security Guides For Your Team

Your server is configured to trust any website that contacts it, including malicious ones. This means if one of your logged-in users visits a harmful website, that site can silently pull data from your application — such as account details, API keys, or personal information — without the user knowing. Think of it like a bank teller who hands over account information to anyone who calls, as long as they say the right words.

Your server is sending two contradictory security instructions at the same time — one that says 'anyone on the internet can read our responses' and another that says 'include the user's private login credentials.' Browsers are smart enough to refuse this combination, so no one is being harmed right now. But this configuration signals a deeper misunderstanding of how cross-site access controls work, and a developer trying to 'fix' it the wrong way could accidentally create a real vulnerability.
