Full Report
A researcher found that using Anthropic’s Claude Opus 4.7, he could break into the website of Front Gate—used by every festival from Lollapalooza to Bonnaroo—and freely issue any ticket he chose.
Analysis Summary
# Vulnerability: Unauthorized API Access and Privilege Escalation in Front Gate Tickets
## CVE Details
- **CVE ID**: Not explicitly listed in the report (Referenced as a zero-day discovery).
- **CVSS Score**: N/A (Estimated Critical based on impact)
- **CWE**: CWE-284: Improper Access Control / CWE-639: Authorization Bypass Through User-Controlled Key
## Affected Systems
- **Products**: Front Gate Tickets Platform (Live Nation Entertainment subsidiary)
- **Versions**: Production environment as of April 2026
- **Configurations**: Internal API used by entry scanners at festival venues and administrative login portals.
## Vulnerability Description
The vulnerability involved a flaw in how the platform validated permissions for its internal APIs and administrative interfaces. By bypassing standard firewall security controls, an attacker could access an internal API—originally intended only for venue entry scanners—to interact with the ticketing database. This allowed for privilege escalation to "super-administrator" status, granting full read/write access to customer records and ticket issuance modules.
## Exploitation
- **Status**: Discovered by a researcher; patched by the vendor. No evidence of malicious exploitation in the wild.
- **Complexity**: Low to Medium (Facilitated by AI-assisted vulnerability discovery)
- **Attack Vector**: Network (Public-facing login portal/API endpoint)
## Impact
- **Confidentiality**: High (Access to millions of customer and staff records)
- **Integrity**: High (Ability to freely issue high-value tickets and modify account status)
- **Availability**: Low (No direct evidence of system-wide disruption, though administrative override was possible)
## Remediation
### Patches
- **Front Gate Tickets Platform Update**: The vendor reported that the issue was resolved within 24 hours of the researcher's disclosure.
### Workarounds
- **Strict IP Whitelisting**: Restricting access to internal APIs (used by venue scanners) to known, authorized network ranges.
- **Enhanced API Authentication**: implementing robust token-based authentication for all non-consumer-facing endpoints.
## Detection
- **Indicators of Compromise**: Unusually high volumes of "Platinum" or "VIP" tickets issued from a single administrative account; administrative logins from unrecognized IP addresses.
- **Detection Methods**: Monitoring audit trails for manual ticket generation events and reviewing API logs for bypassed firewall signatures.
