Security researcher Ben Carroll discovered a critical SQL injection vulnerability in Front Gate, the ticketing platform serving major music festivals, and leveraged Anthropic’s Claude Opus 4.7 AI model to bypass the site’s web application firewall. What emerged was a chain of exploits that could have allowed an attacker to issue unlimited free tickets to events including Bonnaroo — and exposed the personal data of potentially millions of customers.
The Discovery: SQL Injection Blocked by a Firewall
Carroll, who specializes in finding web vulnerabilities, began probing Front Gate’s web domain for security flaws. He quickly identified what appeared to be a SQL injection vulnerability — a class of attack that allows an attacker to inject malicious SQL commands into input fields, forcing the backend database to execute unintended operations. In this case, the flaw could have enabled an attacker to extract sensitive customer data stored in the database. However, a web application firewall (WAF) deployed on the site initially prevented Carroll from exploiting the vulnerability directly.
Claude Opus 4.7 Generated the Bypass Automatically
Unable to defeat the WAF on his own, Carroll turned to Claude Opus 4.7, then the most advanced AI model Anthropic had made publicly available. He asked the model to find a way around the firewall. Claude produced a working exploit technique that Carroll himself did not initially understand. “It was the first time, really, that I had a vulnerability that I didn’t fully understand,” Carroll said. “I had to go back and read what Claude had written to understand the bypass, because I didn’t write it. Claude did it completely by itself.”
The AI had determined that a nested SQL query — a query embedded inside another SQL query — could evade the firewall’s detection rules. From there, Claude wrote a script that enumerated samples from a table containing 500 databases of exposed customer records. Carroll assessed that the vulnerability would have granted access to the personal information of millions of Front Gate customers, including names, email addresses, and mailing addresses. Credit card details were not exposed, according to his findings.
From Data Access to Full Administrative Takeover
With access to staff account data, Carroll escalated the attack. He located a super administrator account, triggered a password reset request, and retrieved the reset code stored in the site’s backend database. Using that code, he confirmed the reset and set a new password, effectively taking over the administrator account.
Once inside, Carroll navigated to the ticketing interface for Bonnaroo, one of the largest U.S. music festivals, and began adding the most expensive tickets available as complimentary entries to a shopping cart. He demonstrated that the same method could be applied to any event managed through the platform. Carroll did not complete an order or issue any actual tickets, citing concerns about crossing into fraudulent activity.
The Absence of Basic Authentication Controls
Carroll expressed surprise at how straightforward the takeover method proved. The platform lacked two-factor authentication, meaning any compromised, stolen, or guessed password would be sufficient to gain full access without additional verification. “There’s just this one centralized company issuing all tickets for every single festival,” Carroll noted. “And even without this vulnerability, if you knew someone’s password, you could just log in without any verification and issue free tickets.”
Perhaps more troubling, Carroll observed that Front Gate did not appear to have conducted proper security auditing of its own systems — either through human penetration testers or through AI-assisted vulnerability discovery, which has made bug hunting significantly more accessible. “It just feels concerning when you think these very professional music festivals with professional websites are well-run,” he said. “Then you get access, and you realize it’s all held together by duct tape and prayers.”
SQL Injection as an Attack Vector
SQL injection remains one of the most well-documented and preventable classes of web application vulnerabilities. It typically occurs when user-supplied data is concatenated directly into SQL queries without proper sanitization or parameterized handling. Despite decades of awareness and tooling to prevent it, SQL injection continues to appear in production systems — particularly in legacy codebases or rapidly built platforms where security testing has been deprioritized.
The intervention of an AI model in this case illustrates a broader shift in the threat landscape: attackers can now use generative AI to craft sophisticated exploits, including WAF bypasses, without requiring deep manual expertise in database internals or evasion techniques. What once demanded hours of manual trial and error can now be accomplished in seconds through natural language prompts.
What Affected Users Should Do Now
Anyone who has purchased tickets through Front Gate for music festivals, concerts, or live events should take immediate steps to secure their accounts and monitor for misuse. Change your account password to a strong, unique credential that you do not reuse across other services. Enable two-factor authentication on any platform that offers it — and if a service does not, consider whether you want to continue using it. Monitor your email accounts for password reset notifications or login attempts you did not initiate. If you use a password manager — which is strongly recommended — ensure it stores credentials in an end-to-end encrypted, zero-knowledge vault. For accessing ticketing websites on public Wi-Fi at festival grounds, use a reputable VPN service with a verified no-logs policy, AES-256 encryption, and a kill switch to prevent data interception. Finally, consider using a dedicated email alias for ticketing services to limit the blast radius of any future data exposure.
The Front Gate incident underscores a sobering reality for the live events industry: even premium ticketing infrastructure may rest on brittle security foundations, and the combination of simple vulnerabilities with increasingly capable AI tools leaves little room for complacency.
