How a single configuration error exposed the Arc browser to remote exploits
In short: A major security flaw in the Arc browser recently allowed attackers to execute malicious JavaScript on any website. This card explores how a simple backend misconfiguration created a massive opening for hackers.
The vulnerability stemmed from a Firebase misconfiguration, highlighting a common pitfall when using rapid development tools. By failing to properly secure the backend environment, the browser became susceptible to remote code execution, where an attacker could run scripts on any site a user visited.
This incident serves as a critical reminder for developers that even robust front-end software can be compromised by basic mistakes in cloud infrastructure and database permissions.
