HIGH 8.5
CVE-2026-71272 is a high-severity flaw (CVSS 8.5) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
Memos' webhook dispatch function safeDialContext (internal/webhook/webhook.go) resolves the target hostname via net.DefaultResolver.LookupHost and validates the resulting IPs against reserved ranges, but then dials net.JoinHostPort(host, port) using the original hostname rather than the already-validated IP address.
