This fix addresses a critical security vulnerability where HTTP requests
could hang indefinitely, potentially causing denial of service.
Changes:
- Added 10-second timeout to version check API call
- Added 10-second timeout to GitHub pull request API call
- Added 30-second timeout to data file downloads (larger timeout for data)
- Added 10-second timeout to exclusions list download
Impact:
- Prevents infinite hangs that could freeze the application
- Improves user experience with predictable response times
- Fixes security issue flagged by Bandit static analysis (B113)
- Makes the application more robust in poor network conditions
The timeouts are conservative enough to work with slow connections
while preventing indefinite blocking that could be exploited.
