@DonnieBLT I'll implement a "Private Bug" checkbox feature that encrypts bug reports to keep them secure. Here's the full implementation:
1. Model Changes
First, let's add a new field to the Issue model:
# Add to website/models.py in the Issue class
# Just after is_hidden field:
is_private = models.BooleanField(default=False, help_text="If checked, this bug will be encrypted and only visible to the reporter and admins")
encrypted_description = models.TextField(null=True, blank=True)
encrypted_markdown_description = models.TextField(null=True, blank=True)
2. Django Settings Update
Add encryption key to your settings file (use a secure random key in production):
# Add to settings.py
# Generate a new key for production with: python -c "from django.core.signing import Signer; print(Signer().sign('encryption-key'))"
ENCRYPTION_KEY = 'your-secure-encryption-key'
3. Template Changes
Add the "Private Bug" checkbox to the report.html template:
<!-- Add after the "Report Anonymously" checkbox in website/templates/report.html -->
<div class="flex items-center gap-2 mt-2">
<input id="is_private"
type="checkbox"
name="is_private"
class="w-5 h-5 rounded-lg text-[#e74c3c] cursor-pointer">
<p for="is_private"
class="font-medium text-gray-900 cursor-pointer select-none">
{% trans "Private Bug (Encrypted)" %}
</p>
<i class="fas fa-info-circle text-gray-500 ml-1 cursor-help"
title="{% trans 'When checked, this bug report will be encrypted and only visible to you and administrators' %}"></i>
</div>
4. Create Encryption Utility
Create a new file for encryption utilities:
# website/utils/encryption.py
from django.conf import settings
from cryptography.fernet import Fernet
import base64
from django.utils.encoding import force_bytes, force_str
def get_encryption_key():
"""Generate a Fernet key from the settings encryption key"""
# Create a 32-byte key from the settings key
key = base64.urlsafe_b64encode(force_bytes(settings.ENCRYPTION_KEY.ljust(32)[:32]))
return key
def encrypt_text(text):
"""Encrypt text using Fernet symmetric encryption"""
if not text:
return None
try:
f = Fernet(get_encryption_key())
encrypted_text = f.encrypt(force_bytes(text))
return force_str(encrypted_text)
except Exception as e:
# Log the error but don't expose encryption details
print(f"Encryption error: {str(e)}")
return None
def decrypt_text(encrypted_text):
"""Decrypt Fernet-encrypted text"""
if not encrypted_text:
return None
try:
f = Fernet(get_encryption_key())
decrypted_text = f.decrypt(force_bytes(encrypted_text))
return force_str(decrypted_text)
except Exception as e:
# Log the error but don't expose encryption details
print(f"Decryption error: {str(e)}")
return "*** Encrypted content ***"
5. Update Views for Handling Private Bugs
Update the IssueCreate view and form handling:
# Update in website/views/issue.py
from website.utils.encryption import encrypt_text, decrypt_text
class IssueCreate(IssueBaseCreate, CreateView):
model = Issue
fields = ["url", "description", "domain", "label", "markdown_description", "cve_id", "is_private"]
template_name = "report.html"
# Rest of the class remains the same...
class IssueBaseCreate(object):
def form_valid(self, form):
score = 3
obj = form.save(commit=False)
obj.user = self.request.user
domain, created = Domain.objects.get_or_create(
name=obj.domain_name.replace("www.", ""),
defaults={"url": "http://" + obj.domain_name.replace("www.", "")},
)
obj.domain = domain
# Handle private/encrypted bugs
if self.request.POST.get("is_private"):
obj.is_private = True
# Encrypt sensitive data
obj.encrypted_description = encrypt_text(obj.description)
obj.encrypted_markdown_description = encrypt_text(obj.markdown_description)
# Replace original content with placeholder text
obj.description = "[Private bug report - requires authentication to view]"
if obj.markdown_description:
obj.markdown_description = "[Private bug report - requires authentication to view]"
# Rest of the method remains the same...
6. Create Model Method for Secure Access
Add a method to the Issue model for secure decryption:
# Add to Issue model in website/models.py
def get_decrypted_description(self, user=None):
"""Get decrypted description if user has permission"""
from website.utils.encryption import decrypt_text
# Allow access to the reporter or staff/admin users
has_permission = (
(user and user.is_authenticated and (user == self.user or user.is_staff)) or
(not self.is_private)
)
if self.is_private and has_permission and self.encrypted_description:
return decrypt_text(self.encrypted_description)
elif self.is_private and not has_permission:
return "[Private bug report - requires authentication to view]"
else:
return self.description
def get_decrypted_markdown_description(self, user=None):
"""Get decrypted markdown description if user has permission"""
from website.utils.encryption import decrypt_text
# Allow access to the reporter or staff/admin users
has_permission = (
(user and user.is_authenticated and (user == self.user or user.is_staff)) or
(not self.is_private)
)
if self.is_private and has_permission and self.encrypted_markdown_description:
return decrypt_text(self.encrypted_markdown_description)
elif self.is_private and not has_permission:
return "[Private bug report - requires authentication to view]"
else:
return self.markdown_description
7. Update Issue Detail View
Modify the issue detail template to use decrypted content:
# Update in views or context processors to provide decrypted content
def get_issue_detail(request, slug):
issue = get_object_or_404(Issue, pk=slug)
# Use decrypted content if user has permission
description = issue.get_decrypted_description(request.user)
markdown_description = issue.get_decrypted_markdown_description(request.user)
context = {
'issue': issue,
'description': description,
'markdown_description': markdown_description,
# Other context data...
}
return render(request, 'issue.html', context)
8. API Security Updates
For the API, add a filter to exclude private bugs for unauthorized users:
# Update API views/serializers to handle private bugs
class IssueViewSet(viewsets.ModelViewSet):
# Existing code...
def get_queryset(self):
queryset = Issue.objects.all()
# Filter out private bugs unless the user is staff or the bug owner
if not self.request.user.is_staff:
queryset = queryset.filter(
Q(is_private=False) |
Q(is_private=True, user=self.request.user)
)
return queryset
# Add permission or modify serializer to handle encrypted fields
9. Add Database Migration
# Generate migration:
# python manage.py makemigrations website --name add_private_bug_fields
This complete implementation ensures private bugs are encrypted, only accessible to authorized users, and not exposed through the API to unauthorized users.
[!TIP] For best results, initiate chat on the files or code changes.

🏁 Script executed:
#!/bin/bash
# Let's check how files are currently encrypted in the codebase (if any)
rg "encrypt|decrypt" --type py
Length of output: 749
@DonnieBLT I'll extend our private bug implementation to also encrypt image attachments. Here's how we'll do it:
1. Add Encrypted Image Fields
First, let's add fields to store encrypted images:
# Add to website/models.py in the IssueScreenshot model
encrypted_image_data = models.BinaryField(null=True, blank=True)
is_encrypted = models.BooleanField(default=False)
2. Enhance Encryption Utilities
Let's expand our encryption utility to handle image files:
# website/utils/encryption.py - Add these functions to the file we created earlier
def encrypt_image(image_file):
"""Encrypt an image file and return the encrypted data"""
if not image_file:
return None
try:
# Read image data
image_data = image_file.read()
# Reset file pointer for other operations
if hasattr(image_file, 'seek'):
image_file.seek(0)
# Encrypt the image data
f = Fernet(get_encryption_key())
encrypted_data = f.encrypt(image_data)
return encrypted_data
except Exception as e:
print(f"Image encryption error: {str(e)}")
return None
def decrypt_image(encrypted_data):
"""Decrypt image data and return it"""
if not encrypted_data:
return None
try:
f = Fernet(get_encryption_key())
decrypted_data = f.decrypt(encrypted_data)
return decrypted_data
except Exception as e:
print(f"Image decryption error: {str(e)}")
return None
def serve_decrypted_image(encrypted_data, original_filename, user=None, issue=None):
"""Create a temporary image file and serve it with proper content type"""
from django.http import HttpResponse, Http404
if not encrypted_data:
raise Http404("Image not found")
# Check permission (if user and issue are provided)
if issue and issue.is_private:
if not user or not user.is_authenticated or (user != issue.user and not user.is_staff):
raise Http404("You don't have permission to view this image")
# Decrypt image data
decrypted_data = decrypt_image(encrypted_data)
if not decrypted_data:
raise Http404("Image could not be decrypted")
# Determine content type based on file extension
content_type = "image/jpeg" # Default
if original_filename.lower().endswith('.png'):
content_type = "image/png"
elif original_filename.lower().endswith('.gif'):
content_type = "image/gif"
# Create and return response with the decrypted image
response = HttpResponse(decrypted_data, content_type=content_type)
return response
3. Create Image View Function
Add a view to securely serve encrypted images:
# Add to website/views/issue.py
from django.http import HttpResponse, Http404
from django.shortcuts import get_object_or_404
from website.utils.encryption import serve_decrypted_image
def serve_encrypted_image(request, screenshot_id):
"""Serve an encrypted image if the user has permission"""
screenshot = get_object_or_404(IssueScreenshot, id=screenshot_id)
issue = screenshot.issue
# Check if the screenshot is encrypted
if not screenshot.is_encrypted or not screenshot.encrypted_image_data:
raise Http404("Image not available")
# Serve the decrypted image
return serve_decrypted_image(
screenshot.encrypted_image_data,
screenshot.image.name if screenshot.image else "image.png",
request.user,
issue
)
4. Update URL Configuration
Add URL pattern for serving encrypted images:
# Add to website/urls.py
path('encrypted-image/<int:screenshot_id>/', views.serve_encrypted_image, name='serve_encrypted_image'),
5. Modify IssueScreenshot Model
Add methods to the IssueScreenshot model for handling encrypted images:
# Add to IssueScreenshot model in website/models.py
def get_image_url(self, user=None):
"""Get image URL based on encryption status and user permissions"""
from django.urls import reverse
if not self.is_encrypted:
return self.image.url if self.image else None
# For encrypted images, use the encrypted image endpoint
if self.encrypted_image_data:
return reverse('serve_encrypted_image', args=[self.id])
return None
6. Update Image Upload Process
Modify the form submission handler to encrypt images for private bugs:
# Modify in website/views/issue.py - within the create_issue method
# After processing screenshots but before saving them
# Save screenshots with encryption if needed
for screenshot in self.request.FILES.getlist("screenshots"):
filename = screenshot.name
extension = filename.split(".")[-1]
screenshot.name = (filename[:10] + str(uuid.uuid4()))[:40] + "." + extension
# Create IssueScreenshot object
issue_screenshot = IssueScreenshot(issue=obj)
# Handle encryption for private bugs
if self.request.POST.get("is_private"):
from website.utils.encryption import encrypt_image
# Encrypt the image data
encrypted_data = encrypt_image(screenshot)
if encrypted_data:
issue_screenshot.encrypted_image_data = encrypted_data
issue_screenshot.is_encrypted = True
issue_screenshot.save()
# Store a placeholder image for database consistency
placeholder_path = os.path.join(settings.STATIC_ROOT, 'img', 'encrypted-placeholder.png')
if os.path.exists(placeholder_path):
with open(placeholder_path, 'rb') as placeholder_file:
issue_screenshot.image.save(f"encrypted_{screenshot.name}", File(placeholder_file), save=True)
else:
# Create a minimal placeholder image if the file doesn't exist
from django.core.files.base import ContentFile
issue_screenshot.image.save(f"encrypted_{screenshot.name}", ContentFile(b""), save=True)
else:
# Regular non-encrypted screenshot
default_storage.save(f"screenshots/{screenshot.name}", screenshot)
issue_screenshot.image = f"screenshots/{screenshot.name}"
issue_screenshot.save()
7. Update Template for Issue Detail
Modify the issue detail template to use the secure image URL method:
<!-- Update in image rendering sections of issue detail templates -->
{% if screenshot.is_encrypted %}
<img src="{% url 'serve_encrypted_image' screenshot.id %}" alt="Encrypted Screenshot" class="screenshot">
{% else %}
<img src="{{ screenshot.image.url }}" alt="Screenshot" class="screenshot">
{% endif %}
8. Update API Endpoints
Modify the API to handle encrypted images:
# Update in website/api/views.py
def get_issue_info(self, request, issue):
# Existing code...
# Handle screenshots with encryption awareness
screenshots = []
# Main screenshot on Issue model
if issue.screenshot and not issue.is_private:
screenshots.append(request.build_absolute_uri(issue.screenshot.url))
# Additional screenshots from IssueScreenshot model
for screenshot in issue.screenshots.all():
if screenshot.is_encrypted:
# Only include encrypted screenshots for authorized users
if request.user.is_authenticated and (request.user == issue.user or request.user.is_staff):
screenshots.append(request.build_absolute_uri(
reverse('serve_encrypted_image', args=[screenshot.id])
))
else:
screenshots.append(request.build_absolute_uri(screenshot.image.url))
# Rest of the existing code...
9. Add Database Migration
# Generate migration:
# python manage.py makemigrations website --name add_encrypted_image_fields
10. Create Placeholder Image
Create a simple placeholder image to use for encrypted images:
# Create a basic placeholder image during deployment or add to source control
from PIL import Image, ImageDraw, ImageFont
img = Image.new('RGB', (300, 200), color=(240, 240, 240))
d = ImageDraw.Draw(img)
d.text((100, 80), "Encrypted Image", fill=(100, 100, 100))
img.save('website/static/img/encrypted-placeholder.png')
This implementation ensures that:
- Images for private bugs are encrypted in storage
- Only authorized users (the reporter and admins) can view the decrypted images
- The system maintains thumbnails and placeholders for UI consistency
- The API respects encryption status when returning image URLs
Would you like me to expand on any specific part of this implementation?
