Can Railway apps be hacked?

Railway-Specific Attack Vectors

These are the paths attackers actually take into Railway applications — not a generic OWASP list, but what automated scanners and security researchers find when they look at Railway apps specifically, given the stack (Postgres as the database):

1. **Public Database Endpoints**: Databases accessible from internet without Private Networking.

2. **Connection String Logging**: Database URLs with credentials visible in logs.

3. **Shared Infrastructure Risks**: Free tier runs on shared infrastructure.

4. **Auto-Deploy Without Review**: Git push auto-deploys without security review.

5. **Volume Data Persistence**: Deleted services may leave data on volumes.

**Postgres-Specific Risk**: Railway apps that expose Postgres directly (via API or PostgREST-style layers) need row-level policies or a middleware that filters by user. Without either, a single SQL-injection or IDOR bug leaks the whole database.

How these issues get discovered

This isn't targeted — automated scanners run across the entire internet looking for known patterns, and Railway apps surface like everything else. Your hosting provider's fingerprint in response headers makes the underlying stack easy to identify. Once identified, the scanner probes the specific vulnerability classes listed above.

What a security scan of a Railway app looks at

• **Secrets Management** — Check Railway secrets configuration.
• **Database Security** — Verify database access controls.
• **Network Config** — Review public/private networking.
• **Container Security** — Analyze container configuration.
