ip-address: ip-address: Inconsistent IP address parsing leads to Server-Side Request Forgery (SSRF) and trust-boundary bypass

A flaw was found in the ip-address library. This library incorrectly interprets IPv4 address octets with leading zeros as decimal, while standard network parsers interpret them as octal. This inconsistency can cause applications to misclassify network targets, allowing a remote attacker to bypass...

CVE-2026-68402

Summary: CVE-2026-68402 affects the Linux kernel Wi‑Fi stack (cfg80211). A flaw in cfg80211_is_element_inherited() may read the first byte of an extension element (elem->data[0]) without confirming the element has data, allowing a crafted Wi‑Fi frame to trigger a one‑octet slab‑out‑of‑bounds r...

CVE-2026-69192

ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. Prior to 10.3.1, Address4 accepts an octet written with a leading zero and decodes it as decimal, while the WHATWG URL host parser, inetaton, and getaddrinfo all decode a leading zero as octal. The library...
