Open-Source vs. Cloud-Managed License Systems: Security & DDoS Vulnerabilities

The Security Risks of Self-Hosting#

Self-hosted open-source license scripts often contain unpatched SQL injection flaws, lack memory protection, and crash under DDoS traffic. Common issues:

• SQL injection: User-supplied license keys concatenated into raw SQL queries.
• No rate limiting: Brute-force key enumeration attacks.
• Plaintext webhooks: Payment callbacks without signature verification.
• Single-server dependency: One VPS crash takes down your entire auth system.
