CVE-2026-24398

CVE-2026-24398 — Hono IPv4 address validation bypass : Prior to 4.11.7, IP Restriction Middleware fails to validate IPv4 octets in the src/utils/ipaddr.ts code paths, due to a permissive IPv4_REGEX and an unsafe convertIPv4ToBinary function. This allows crafting malformed IPs that can bypass IP-b...
