CVE-2026-55787

The flyto-core execution kernel is vulnerable to Server-Side Request Forgery (SSRF) in versions prior to 2.26.3 due to an incomplete SSRF guard in src/core/utils.py. The validate_url_ssrf and is_private_ip functions fail to unwrap IPv6 transition addresses (such as IPv4-mapped , 6to4 , and NAT64 ...

Security Bulletin:ip-address IPv4-mapped/NAT64 IPv6 Address SSRF Vulnerability Fix in 10.2.1

Summary ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. Versions 10.1.1 through 10.2.0 are vulnerable to SSRF through misclassification of IPv4-mapped/NAT64 IPv6 addresses. Address6.getType classifies an address by matching it against a table of known...

CVE-2026-90711

A flaw was found in proxy-addr. When an application defines trusted proxy subnets using IPv4-mapped IPv6 addresses with an improper prefix length, the subnet parser fails open and erroneously treats all incoming network addresses as trusted. A remote, unauthenticated attacker can exploit this...

GHSA-JQCG-44MW-7W3H proxy-addr vulnerable to IP spoofing via IPv4-mapped IPv6 trust subnet

Impact proxy-addr determines which network hops are trusted proxies so that X-Forwarded-For can be believed. When an application configures a trust subnet as an IPv4-mapped IPv6 address with a short prefix, such as ::ffff:10.0.0.0/8 the correct spelling is ::ffff:10.0.0.0/104, the subnet compiles...
