CVE-2026-72761 Webhook SSRF guard bypassed by IPv6 transition addresses (NAT64/6to4/Teredo pass is_global check) in vulnerability-lookup

The webhook URL validator in website/notifications/webhooks.py uses ip.isglobal to reject non-public addresses after DNS resolution. IPv6 transition addresses NAT64 64:ff9b::/96, 6to4 2002::/16, Teredo 2001:0000::/32 are classified as globally routable by IANA, so isglobal returns True even when...

CVE-2026-72761

The CVE affects the webhook URL validator in website/notifications/webhooks.py, which uses ip.is_global after DNS resolution. IPv6 transition addresses (NAT64 64:ff9b::/96, 6to4 2002::/16, Teredo 2001:0000::/32) are categorized as globally routable by IANA, causing is_global to return True even w...

CVE-2026-68322

CVE-2026-68322 concerns the Linux kernel RDS subsystem. When IPv6 is explicitly disabled with ipv6.disable=1, inet6_addr_lst is never initialized, because inet6_init() exits before addrconf_init() runs. This leads to a NULL dereference in __ipv6_chk_addr_and_flags() when attempting to bind an RDS...
