Security Bulletin:ip-address IPv4-mapped/NAT64 IPv6 Address SSRF Vulnerability Fix in 10.2.1

Summary ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. Versions 10.1.1 through 10.2.0 are vulnerable to SSRF through misclassification of IPv4-mapped/NAT64 IPv6 addresses. Address6.getType classifies an address by matching it against a table of known...

K000163541: ip-address library vulnerability CVE-2026-42338

Security Advisory Description ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. Prior to 10.1.1, Address6.group and Address6.link do not HTML-escape attacker-controlled content before embedding it in the HTML strings they return, and...

ip-address: isInSubnet() and isHostInSubnet() compare addresses of different families as if they shared an address space, allowing an allowlist check to admit an address outside its range

Summary isInSubnet and isHostInSubnet accept an address of either family and compare masked binary strings without checking that both operands are the same family. Address4 pads to 32 bits and Address6 to 128, so whenever the leading bits agree the strings are equal: new...

NPM: ip-address: Address6 builds a parse diagnostic proportional to the input with no length bound, allowing a single long string to stall or crash the process

GHSA-H3MG-XC3C-68PW ip-address: Address6 builds a parse diagnostic proportional to the input with no length bound, allowing a single long string to stall or crash the process

Summary new Address6 and Address6.isValid place no bound on the length of the string they parse. When the string contains a character that cannot appear in an IPv6 address, the parser builds a diagnostic that wraps every such character in a 34-byte , so the work and the memory scale with the inpu...

SUSE CVE-2026-101910

ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. From 10.2.0 until 10.5.1, the Address6 isPrivate classifier in src/ipv6.ts does not recognize the NAT64 local-use range 64:ff9b:1::/48. Applications that combine isPrivate, isLoopback, and isLinkLocal for ...

SUSE CVE-2026-101911

ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. Prior to 10.7.1, the Address6 constructor, Address6.isValid, and parse code in src/ipv6.ts accept unbounded strings and expand invalid characters through REBADCHARACTERS into large diagnostics. Material...

SUSE CVE-2026-101913

ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. Prior to 10.5.1, the Address6 isLinkLocal method in src/ipv6.ts recognizes only fe80::/64 instead of the complete fe80::/10 IPv6 link-local range. An attacker-controlled address elsewhere in fe80::/10 can...

NPM: ip-address: Address6.isLinkLocal() recognizes fe80::/64 rather than fe80::/10, allowing SSRF and trust-boundary bypass to on-link hosts

NPM: ip-address: Address6.isLinkLocal recognizes fe80::/64 rather than fe80::/10, allowing SSRF and trust-boundary bypass to on-link hosts vulnerability discovered by ? in WordPress Npm ip-address versions = 10.5.0...

ip-address: Address6.isLinkLocal() recognizes fe80::/64 rather than fe80::/10, allowing SSRF and trust-boundary bypass to on-link hosts

Summary Address6.isLinkLocal recognizes fe80::/64 rather than fe80::/10. Link-local unicast is the whole /10 under RFC 4291 §2.4 and the IANA IPv6 Special-Purpose Address Registry, so the method returns false for every link-local address outside the one /64 that stateless address autoconfiguratio...

GHSA-2VR4-CQ9G-PVRC ip-address: no classifier recognizes the NAT64 local-use range 64:ff9b:1::/48, allowing SSRF and trust-boundary bypass

Summary No classifier on Address6 recognizes the NAT64 local-use range 64:ff9b:1::/48 RFC 8215. isPrivate, isLoopback, isLinkLocal and their siblings all return false for every address in it, so an internal IPv4 destination written through a local-use NAT64 prefix 64:ff9b:1:7f00:0:100:: for...
