CVE-2026-73087
Dozzle: SSRF guard bypass via IPv6 transition addresses (6to4/NAT64/Teredo) in webhook notification dispatcher
Impact
Dozzle is a realtime log viewer for docker containers. From 10.5.2 until 10.6.15, the isBlockedIP SSRF guard in internal/notification/dispatcher/webhook.go, used by safeDialContext for webhook notification URLs, does not inspect IPv4 addresses embedded in 6to4, NAT64, Teredo, or IPv4-compatible IPv6 addresses, allowing an authenticated user to reach loopback or link-local targets that the guard intends to block. This issue is fixed in version 10.6.15.
