PII data Leakage through hackerone reports
How it was found
Summary:
I found PII data leakage through the HackerOne report. I found a link in one of the disclosed report that allow me to get the address and phone numbers of security researchers. Here I got the address and phone number of ████ (███)
Vulnerability Name: PII data Leakage through
Steps to reproduce:
—>Just visit ███ —>You will find a link swag link there. (Refer: Screenshot 1) —>Now visit the swag link ie. ██████████ and add a parameter there ██████████ —> link becomes : ████████ —>You will get the PII of researchers. (Refer: Screenshot 2)
Fix
1.)████████ should be informed that the data might have leaked. 2.)Link should be redacted. 3.) When hackerone provides swag to researchers they should mention to keep the link strictly confidential , same information should also be provided to the programs on HackerOne , that offer swag.
Impact
An attacker can get sensitive information about the other researchers like their addresses and phone number.
