to version 6.1.7 or higher.
grumpydictator/firefly-iii is a personal finances manager.
Affected versions of this package are vulnerable to Arbitrary Code Execution via the Export Data
feature which generates a CSV file. An attacker can execute arbitrary commands on a user's machine by entering a specially crafted payload into one of the fields, which is then executed when the CSV file is opened with Excel or other software that supports macros.
Note:
This is only exploitable if a user downloads and opens a CSV file containing the malicious payload on their local machine.
