Hey @GYFX35 - I've reviewed your changes and found some issues that need to be addressed.
Blocking issues:
- Identified a Private Key, which may compromise cryptographic security and sensitive data encryption. (link)
- Identified a Private Key, which may compromise cryptographic security and sensitive data encryption. (link)
- Private Key detected. This is a sensitive credential and should not be hardcoded here. Instead, store this in a separate, private file. (link)
- Validate and sanitize image data before saving. (link)
General comments:
- The VAPID private/public keys shouldn’t be hard-coded in config.py—load them from environment variables or a secure vault instead of committing them to source control.
- Consider refactoring the inline JS for push notifications and camera capture into separate static JS modules for better maintainability and caching.
- Calling
send_push_notificationsynchronously in your route handlers can slow down responses—offload push dispatch to a background worker and add logic to clean up invalid subscriptions.

Consider logging push notification errors more robustly.
Using a logging framework instead of print statements will ensure errors are properly recorded and easier to track in production.
