Note to huntr moderators (if any!): There have been 4 different vulnerability reports for the same issue, but each report for a different field on the same page ... all 4 reports were fixed by a single commit .. so I believe all 4 reports should be merged into one. But if you don't want to do so, I'm happy to get rewarded 4 times for the same fix ;)
