Summary
Teredo clients, when following item 6 of RFC4380 section 5.2.3, start direct IPv6 connectivity tests (aka ping tests) in response to packets from non-Teredo source addresses, which might allow remote attackers to induce Teredo clients to send packets to third parties.
Exploit prediction
12.07% chance of exploitation in the next 30 days, higher than 96% of all scored CVEs (FIRST EPSS, 2026-11-08).
