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 –...

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...

The various “Is” methods IsPrivate, IsLoopback, etc. did not work as expected for IPv4-mapped IPv6 addresses. They returned false for addresses that would return true in their traditional IPv4 form...

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...

Hono has incorrect IP matching in ipRestriction() for IPv4-mapped IPv6 addresses

Summary ipRestriction does not canonicalize IPv4-mapped IPv6 client addresses e.g. ::ffff:127.0.0.1 before applying IPv4 allow or deny rules. In environments such as Node.js dual-stack, this can cause IPv4 rules to fail to match, leading to unintended authorization behavior. Details The middlewar...
