XSS security issue - Caspar Leo - 04-03-2017 Hey, noticed a XSS vulnerability in users/edit_profile.php on line 45: $newBio = $_POST['bio']; Should be: $newBio = Input::get('bio'); Otherwise we got some naked & public scripts in users bios XSS security issue - mudmin - 04-03-2017 Yep! You are right. Thank you for this. I will get this on the todo list. THANK YOU! XSS security issue - mudmin - 04-16-2017 Actually, I double checked this. The problem with using Input::get there is that it would strip out all your formatting and punctuation. You'll noticed that the data is sanitized as it's displayed on the profile.php instead... $usbio = html_entity_decode($thatUser->bio); The XSS vulnerability should be taken care of by the token check done in the validation on line 41 unless you're seeing something I'm not. I could definitely be missing something here. Let me know what you think.
