AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a prototype pollution issue in the CSV parsing logic during import. It can cause untrusted file paths to be introduced into the shell.openExternal function after certain user actions, potentially allowing a "1-click" command execution.
How can this vulnerability impact me? :
The vulnerability can lead to unintended command execution with minimal user interaction ("1-click"), which may allow attackers to execute commands on the affected system by exploiting untrusted file paths introduced during CSV import.
