CVE-2026-44492

A flaw was found in Axios, a promise-based HTTP client. This vulnerability occurs because Axios does not properly normalize IPv4-mapped IPv6 addresses. When a NOPROXY setting is configured to block direct access to specific IPv4 addresses, an attacker can bypass this restriction by using the...

CVE-2026-44492

Axios is a promise based HTTP client for the browser and Node.js. Prior to 0.32.0 and 1.16.0, Axios does not normalise IPv4-mapped IPv6 addresses. When NOPROXY lists an IPv4 address such as 127.0.0.1 or 169.254.169.254, a request URL using the IPv4-mapped IPv6 form ::ffff:7f00:1, ::ffff:a9fe:a9fe...

Sync-in Server: SSRF protection bypass via IPv4-mapped IPv6 addresses in regExpPrivateIP

Summary: The private IP blocklist regex used in the URL download feature does not match IPv4-mapped IPv6 addresses e.g. ::ffff:127.0.0.1, allowing SSRF protection to be bypassed on dual-stack systems. Affected components backend/src/applications/files/services/files-manager.service.ts –...

GHSA-XRHX-7G5J-RCJ5 Hono: IP Restriction bypasses static deny rules for non-canonical IPv6

Summary The ip-restriction middleware hono/ip-restriction compares incoming IP addresses against configured deny and allow rules using string equality after partial normalization. Non-canonical IPv6 representations of an address already listed in a static rule — such as compressed forms,...

axios's shouldBypassProxy does not recognize IPv4-mapped IPv6 addresses, allowing NO_PROXY bypass (incomplete fix for CVE-2025-62718)

Summary shouldBypassProxy, introduced in v1.15.0 to fix CVE-2025-62718, does not normalise IPv4-mapped IPv6 addresses. When NOPROXY lists an IPv4 address such as 127.0.0.1 or 169.254.169.254, a request URL using the IPv4-mapped IPv6 form ::ffff:7f00:1, ::ffff:a9fe:a9fe still routes through the...

CVE-2026-40199

Net::CIDR::Lite versions before 0.23 for Perl mishandles IPv4 mapped IPv6 addresses, which may allow IP ACL bypass. packipv6 includes the sentinel byte from packipv4 when building the packed representation of IPv4 mapped addresses like ::ffff:192.168.1.1. This produces an 18 byte value instead of...

CVE-2026-40199

CVE-2026-40199 affects Net::CIDR::Lite before 0.23 for Perl. The bug: _pack_ipv6() incorrectly reuses the IPv4 sentinel byte when encoding IPv4-mapped IPv6 addresses (::ffff: x.x.x.x), producing an 18-byte packed value instead of 17. This mislength misaligns the IPv4 part and breaks mask operatio...
