In the fast-paced world of modern software development, grasping the full scope of an application is essential for managing an application security program. This entails having visibility into all the application assets involved in building the app, knowing their ownership, and understanding their importance to the development process and the broader business.

Welcome, fellow developers! In this blog post, we are going to delve deep into the world of application security, specifically focusing on a vulnerability that can deteriorate FastAPI security: Denial of service (DoS) caused by insecure regular expressions (regex).

SQL injection (SQLi) is one of the most severe security vulnerabilities in web applications. It occurs when an attacker is able to manipulate the SQL queries executed by an application by injecting malicious SQL code into user input fields. SQLi can lead to unauthorized access to sensitive data, data corruption, or even complete control over the database server.

In this post, we explore a powerful, yet widely unknown attack vector which has emerged in the last couple of years known as ‘Repo Jacking’. During our research, we discovered the enormous potential to compromise software components with tens of millions of downloads across the Terraform IaC (Infrastructure as Code) and Composer (PHP package registry) ecosystems. Despite its power, Repo Jacking remains under-researched and frequently misunderstood.
