CVE-2026-50248: Unbound Ignored Dnssec Status

A DNS lookup callback receives a DNSSEC validation status but processes a successful response (`LDNS_RCODE_NOERROR`) without checking for `sec_status_bogus`. This allows an attacker to spoof BOGUS responses, bypassing DNSSEC validation boundaries. Ensure the security status is validated prior to trusting the lookup result.
