  • 🚨 Severity: MEDIUM
  • 💡 Vulnerability: Unbounded input length on effective_from and amount_per_h form parameters in handleFuelAdjustmentSave.
  • 🎯 Impact: Risk of CPU and memory resource exhaustion (DoS) when parsing oversized date or decimal strings.
  • 🔧 Fix: Added s.tooLong validation upfront for effective_from (capped at 50 chars) and amount_per_h (capped at maxDecimalLen / 32 chars) in handleFuelAdjustmentSave.
  • ✅ Verification: Added test cases in internal/server/input_limits_test.go and verified all unit tests pass with go test ./....
