Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Insecure Network Configuration: The portmap plugin's nftables backend incorrectly intercepted and DNATed non-local transit traffic due to a missing fib lookup. This allowed accidental exposure or hijacking of routing paths, requiring explicit destination type validations.
Incorrect File Permissions: Host-local IPAM plugin state files were created with world-readable permissions (0644), exposing allocated IP address assignments and metadata to unauthorized local users. Restricting these files to 0600 is critical to preventing local information disclosure.
