The 60-Second TL;DR
GoWasp turns OWASP theory into exploitable reality with Go backend and Vue frontend.
Hands-on breaking reveals why SQLi, mass assignment, CSRF, and template injection persist.
Unique edge: Mirrors early web's trial-by-fire, predicting rise in self-hacking tools.
```
Tokens fix it; validate per-request. SameSite=Lax helps, but pair 'em.
## Can Template Injection Turn User Bios into RCE Nightmares?
Unescaped inputs in Go templates or Vue's `v-html`? Attacker drops `{{7*7}}` — if it evals to 49, you're leaking data. Worse engines execute code.
Always escape. Treat inputs as shrapnel.
This app weaves all these — SQLi logins, mass-assign updates, CSRF deletes, template tricks — into a realistic CRUD flow. Modern stacks (Go's net/http, Vue's reactivity) shine, yet vulns persist because security's bolted-on, not baked-in.
Corporate spin calls frameworks 'secure-by-default.' Bull. They're accelerants; you supply the fireproofing.
Run it with Docker for isolation. Exploit guide walks SQLi, then mass-assign to snag admin, CSRF your 'account' away. Secure siblings show patterns: `database/sql` preps, struct tags for binding, `html/template` auto-escapes.
Deeper why: architecture shifted post-Heartbleed. Monoliths hid flaws; microservices + APIs expose 'em. GoWasp mimics that — stateless backend, SPA frontend, real-world blast radius.
Prediction? As Rust/WebAsm hype security, Go's simplicity keeps it dev-favorite — but only if tools like this proliferate. Teams ignoring 'break it yourself' invite breaches.
> If you can break your own system, you’re already one step closer to building something resilient.
Amen.
Scale it: fork for custom vulns, CI/CD scans, pentest drills. It's open-source gold.
## Why Developers Ignore These Till the Breach Hits
Habit. Rush to MVP trumps audits. GoWasp flips that — 30 minutes to vuln heaven, hours to mastery.
Historical parallel: Morris Worm '88 didn't kill ARPANET; it birthed CERT. GoWasp births your inner red-teamer.

Frequently Asked Questions
**What is GoWasp and how do I run it?**
GoWasp is a vulnerable web app in Go and Vue.js for practicing OWASP top vulns. Clone from GitHub, `go mod tidy && go run .`, browse localhost:8080. README has exploits.
**How do I fix SQL injection in Go?**
Use `database/sql` with `db.QueryRowContext(ctx, query, email, password)` — params auto-sanitize. Ditch string concat.
**Does this replace formal security training?**
Nah, complements it. Hands-on cements theory; pair with OWASP ZAP or Burp for pro drills.
Security? Muscle memory from breaking. Who's next?
