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...
