CVE-2026-101912 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

ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. Prior to 10.7.1, the isInSubnet and isHostInSubnet methods in src/common.ts compare masked binary strings without validating that both operands use the same IP family. A cross-family containment check whos...

CVE-2026-101912

The ip-address JavaScript library for parsing and manipulating IPv4 and IPv6 addresses is vulnerable in versions prior to 10.7.1 . The isInSubnet and isHostInSubnet methods in src/common.ts fail to validate that both operands belong to the same IP family when comparing masked binary strings. This...

CVE-2026-101911 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

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...

CVE-2026-101911

The ip-address JavaScript library (versions prior to 10.7.1 ) is vulnerable to a Denial of Service (DoS) condition. The Address6 constructor , Address6.isValid , and the parse code in src/ipv6.ts accept unbounded strings and expand invalid characters via RE_BAD_CHARACTERS into large diagnostics. ...

CVE-2026-101910 ip-address: no classifier recognizes the NAT64 local-use range 64:ff9b:1::/48, allowing SSRF and trust-boundary bypass

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 ...

CVE-2026-101910

The ip-address JavaScript library (versions 10.2.0 through 10.5.1 ) contains a logic flaw in the Address6 isPrivate classifier located in src/ipv6.ts. Specifically, it fails to recognize the NAT64 local-use range 64:ff9b:1::/48. This allows applications that rely on isPrivate, isLoopback, and isL...
