Sentry: Cybersecurity Incident
Publicly exposed Sentry Data Source Names (DSNs) were exploited as an attack vector via AI coding agents (Claude Code, Cursor) through Model Context Protocol integrations to achieve remote code execution and credential exfiltration. Attack succeeded 85% of the time across 100+ organizations; 2,388 organizations identified with publicly discoverable DSNs including 71 in Tranco top-1M and ~27% of Fortune 1000 via Cloudflare MCP alone. Sentry notified June 3, 2026; deployed content filter by June 12 but declined platform-level root-cause remediation.
