Input validation error in ip-address - CVE-2026-54272

Vulnerability identifier: #VU146518

CSH Severity: Medium

CVSS v4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-54272

CWE-ID: CWE-20

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to bypass SSRF and trust-boundary checks.

The vulnerability exists due to improper input validation in Address6 special-property checks when processing IPv4-mapped or NAT64 IPv6 addresses. A remote attacker can supply a crafted IPv6 literal that embeds an internal IPv4 destination to bypass SSRF and trust-boundary checks.

For NAT64 addresses, end-to-end reachability additionally requires a NAT64/DNS64 gateway in the deployment network.
