Over the weekend, word emerged that a hacker breached far-right social media website Gab and downloaded 70 gigabytes of data by exploiting a garden-variety security flaw known as an SQL injection. A quick review of Gab’s open source code shows that the critical vulnerability—or at least one very much like it—was introduced by the company’s chief technology officer.

The change, which in the parlance of software development is known as a “git commit,” was made sometime in February from the account of Fosco Marotto, a former Facebook software engineer who in November became Gab’s CTO. On Monday, Gab removed the git commit from its website. Below is an image showing the February software change, as shown from a site that provides saved commit snapshots.
