Usually (with each PROPER wallet), nothing except for bruteforcing the private key (which does only work if you had a very very weak password or you can remember the majority of your password).
But.. since you are using jaxx you might have another chance.
Jaxx has quite a few vulnerabilities which allow to extract the private keys. You might want to search for one and get/create an exploit to extract the seed / private keys.
And in the future, make sure to have a backup of your mnemonic seed. And please do NOT further use jaxx.
ANYONE can steal your coins if you are using jaxx using simple malware.
In this case, this is helpful for you. But generally this is a worst case scenario.
