Hand-rolled, kettle-boiled, baked to perfection. Worth every minute at the bakery.
Summary
A security researcher details their discovery and disclosure of three vulnerabilities in VSCode extensions and one in VSCode itself (CVE-2022-41042, earning a $7,500 bounty). The article explains the underlying causes of these security flaws, demonstrates working exploits showing how attackers could compromise systems, and provides recommendations for preventing similar vulnerabilities in the future. The content is part of a two-part blog series focused on security research in the VSCode ecosystem.

· 4 pulledThis two-part blog series will cover how I found and disclosed three vulnerabilities in VSCode extensions and one vulnerability in VSCode itself (a security mitigation bypass assigned CVE-2022-41042 and awarded a $7,500 bounty).
We will identify the underlying cause of each vulnerability and create fully working exploits to demonstrate how an attacker could have compromised your machine.
We will also recommend ways to prevent similar issues from occurring in the future.
A few months ago, I decided to assess the security of some VSCode extensions that we frequently use during audits.
