What the vulnerability does

01Description

rotki before 1.44.2 contains a weak key derivation vulnerability that allows attackers to brute-force backups because the premium sync key is a single unsalted SHA-256 of the user password. Attackers who obtain an uploaded backup blob can run GPU-parallel offline password guessing and decrypt the database containing exchange API keys, secrets, wallet addresses and transaction history.
