+date: 2026-08-27
+description: |
+  An application that resolves a hostname an attacker can influence,
+  such as a webhook target or a user-supplied URL, can be made to
+  consume memory without bound. The attacker points a domain at a
+  name server they control and returns responses that the library
+  retains permanently. Repeated lookups grow the process until it
+  runs out of memory and the service stops.

+title: CVE-2026-80213 - Hostname validation bypass
+date: 2026-08-27
+description: |
+  An application that checks a hostname against an allow list or an
+  SSRF filter and then resolves it can be made to look up a domain
+  other than the one it checked. The string that passes validation
+  and the name that reaches the network are not the same, so the
+  connection can end up at a host the application never approved.
+  This requires a hostname that exceeds the DNS length limits, so
+  validation that rejects names longer than 255 octets, or labels
+  longer than 63 octets, is not affected.
