Overview
Affected versions of this package are vulnerable to CSV Injection in the exportToCSV and exportQueryToCSV processes, where user-controlled input from fields such as Payee and Notes is passed to CSV export without neutralizing formula-triggering characters. An attacker can cause confidential data to be exfiltrated or displayed incorrectly by crafting malicious input that, when exported and opened in spreadsheet software, is interpreted as a formula. This can lead to the exposure of sensitive information or manipulation of displayed data when the exported CSV is opened by a victim or shared recipient.
