Published Aug 11, 2026 CVSS 4.0 · 2.3 Low EPSS < 1% KEV · Not listed
Description

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.
