Estimated field mix
On-call staff need a safe response when one peer fails certificate validation.
Estimated field mix
The importer accepts any URL beginning with a trusted-looking string.
Estimated field mix
User-info syntax and encoded separators confuse destination checks.
Estimated field mix

Estimated field mix
A response exceeds memory limits before its declared size can be checked.
Estimated field mix
Each redirect gets a fresh timeout, extending one import indefinitely.
Estimated field mix
