Chaterm before 0.12.1 contains a login cross-site request forgery vulnerability that allows remote attackers to inject login state by sending chaterm:// callbacks without OAuth state validation. Attackers can trigger a crafted callback with attacker-controlled userInfo from a web page, signing the victim into the attacker's account so default data sync uploads saved hosts, passwords, and private keys.
