This commit addresses a critical security issue where malicious Docker Compose
data was being saved to the database before validation occurred.
Problem:
- Service models were saved to database first
- Validation ran afterwards during parse()
- Malicious data persisted even when validation failed
- User saw error but damage was already done
Solution:
1. Created validateDockerComposeForInjection() to validate YAML before save
2. Added pre-save validation to all Service creation/update points:
- Livewire: DockerCompose.php, StackForm.php
- API: ServicesController.php (create, update, one-click)
3. Validates service names and volume paths (string + array formats)
4. Blocks shell metacharacters: backticks, $(), |, ;, &, >, <, newlines
Security fixes:
- Volume source paths (string format) - validated before save
- Volume source paths (array format) - validated before save
- Service names - validated before save
- Environment variable patterns - safe ${VAR} allowed, ${VAR:-$(cmd)} blocked
Testing:
- 60 security tests pass (176 assertions)
- PreSaveValidationTest.php: 15 tests for pre-save validation
- ValidateShellSafePathTest.php: 15 tests for core validation
- VolumeSecurityTest.php: 15 tests for volume parsing
- ServiceNameSecurityTest.php: 15 tests for service names
