Akaunting 3.3.0 contains a stored cross-site scripting vulnerability in custom invoice payment terms. An authenticated Manager can save a crafted custom payment-term value. When an authorized user opens Invoice Settings for the same company, Akaunting inserts the stored value into a client-side event-handler expression, causing attacker-controlled JavaScript to execute in the victim's authenticated origin.
