## Technical details

A stored cross-site scripting (XSS) vulnerability exists in Akaunting versions up to 3.1.21 within the Invoice/Billing component. The vulnerability is caused by improper neutralization of user-supplied input in the 'notes' argument. A remote attacker with low privileges can exploit this by injecting malicious JavaScript that executes when a victim views the affected invoice. While a proof-of-concept has been disclosed, the vendor has reportedly not responded to the disclosure, and no official patch is currently confirmed.
