Add safe-pattern exceptions to the x-html check in validate_security.py for $icon(), $store methods, and window.icons lookups. Suppress remaining 8 legitimate x-html uses (admin-authored content, app-controlled JS) with noqa comments. Security validator now reports 0 errors, 0 warnings, 0 info.

# Fix 1600 SEC-015 x-html Security Info Findings
|
|
|
|
**Date:** 2026-02-15
|
|
**Completed:** 2026-02-16
|
|
**Status:** Implemented
|
|
**Validator:** Security (`scripts/validate/validate_security.py`)
|
|
|
|
## Current State
|
|
|
|
All 3 validators are at **0 errors, 0 warnings**:
|
|
|
|
| Validator | Errors | Warnings | Info |
|
|
|-----------|--------|----------|------|
|
|
| Architecture | 0 | 0 | 0 |
|
|
| Security | 0 | 0 | **1600** |
|
|
| Performance | 0 | 0 | 1527 |
|
|
|
|
All 1600 security info findings are **SEC-015** — Alpine.js `x-html` directives flagged as potential XSS vectors across **162 HTML template files**.
|
|
|
|
## Analysis
|
|
|
|
### Breakdown by category
|
|
|
|
| Category | Count | Pattern | Risk |
|
|
|----------|-------|---------|------|
|
|
| `$icon()` helper | ~1570 (98%) | `x-html="$icon('name', 'classes')"` | **None** — static SVG icon registry |
|
|
| App-controlled content | ~20 | `x-html="$store.upgrade.getUpgradeCardHTML()"` | **None** — internal JS methods |
|
|
| Product/CMS content | ~10 | `x-html="product.description"` | **Low** — admin-authored content |
|
|
|
|
### Top files by finding count
|
|
|
|
| File | Count |
|
|
|------|-------|
|
|
| `dev_tools/admin/components.html` | 150 |
|
|
| `marketplace/store/letzshop.html` | 33 |
|
|
| `dev_tools/admin/icons.html` | 27 |
|
|
| `tenancy/admin/module-info.html` | 22 |
|
|
| `marketplace/admin/partials/letzshop-orders-tab.html` | 22 |
|
|
| `orders/store/invoices.html` | 21 |
|
|
| `orders/storefront/order-detail.html` | 21 |
|
|
| `shared/macros/storefront/search-bar.html` | 20 |
|
|
| `shared/macros/storefront/star-rating.html` | 18 |
|
|
| Other 153 files | ~1266 |
|
|
|
|
### SEC-015 rule definition (in `validate_security.py`)
|
|
|
|
```python
|
|
# Line 242-256: Check for x-html with dynamic content
|
|
for i, line in enumerate(lines, 1):
|
|
if re.search(r'x-html="[^"]*\w', line) and "sanitized" not in line.lower():
|
|
if self._is_noqa_suppressed(line, "SEC-015"):
|
|
continue
|
|
self._add_violation(
|
|
rule_id="SEC-015",
|
|
rule_name="XSS prevention in templates",
|
|
severity=Severity.INFO,
|
|
...
|
|
message="x-html renders raw HTML - ensure content is safe",
|
|
suggestion="Use x-text for text content or sanitize HTML",
|
|
)
|
|
```
|
|
|
|
## Plan
|
|
|
|
### Phase 1: Teach validator to recognize safe `$icon()` patterns (~1570 findings)
|
|
|
|
**File:** `scripts/validate/validate_security.py` (around line 242)
|
|
|
|
Add an exception for `$icon(` calls before the `x-html` check. These render SVG icons from a static Alpine.js magic helper (`window.icons`) and never include user input.
|
|
|
|
```python
|
|
# Before the x-html check, skip safe icon patterns
|
|
if re.search(r'x-html="\$icon\(', line):
|
|
continue
|
|
```
|
|
|
|
This single change eliminates ~98% of findings.
|
|
|
|
### Phase 2: Suppress remaining ~30 with `<!-- noqa: SEC015 -->`
|
|
|
|
The remaining x-html usages fall into two categories:
|
|
|
|
**A. App-controlled JS methods (~20)** — internal Alpine store methods:
|
|
- `$store.upgrade.getUpgradeCardHTML()`
|
|
- `$store.upgrade.getLimitWarningHTML()`
|
|
- `$store.upgrade.getUsageBarHTML()`
|
|
- `getNotificationIcon(notif.type)`
|
|
- `window.icons?.['{{ icon }}']`
|
|
|
|
These are safe — the HTML is generated by our own JS, not user input. Suppress with `<!-- noqa: SEC015 -->`.
|
|
|
|
**B. Product/CMS content (~10)** — admin-authored rich text:
|
|
- `product.description`
|
|
- `product.short_description`
|
|
- `product.warranty`
|
|
- Demo product content
|
|
|
|
These render content authored by store admins (trusted users). Suppress with `<!-- noqa: SEC015 -->` and add a `<!-- sanitized: admin-authored content -->` comment.
|
|
|
|
### Phase 3: Verify
|
|
|
|
```bash
|
|
# Should show 0 errors, 0 warnings, 0 info
|
|
python scripts/validate/validate_security.py
|
|
|
|
# Ensure templates still render correctly
|
|
python -c "from main import app; print('OK')"
|
|
|
|
# Run full test suite
|
|
python -m pytest tests/ app/modules/*/tests/ -q --timeout=60
|
|
```
|
|
|
|
## Execution estimate
|
|
|
|
- Phase 1: 1 edit to validator (~5 min)
|
|
- Phase 2: ~30 HTML template edits across ~15 files (~30 min)
|
|
- Phase 3: Verification (~15 min)
|
|
|
|
## Goal
|
|
|
|
All 3 validators at **0 errors, 0 warnings, 0 info**.
