SurrealDB allows bypass of deny-net flags via DNS resolution

SurrealDB offers http functions that can access external network endpoints. A typical, albeit not recommended configuration would be to start SurrealDB with all network connections allowed with the exception of a deny list. For example, surreal start --allow-net --deny-net 10.0.0.0/8 will allow a...

JLSEC-2026-1164 Deno: `fetch()` API sandbox bypass via missing DNS resolution check

Summary When fetch was called, Deno checked the destination hostname against --deny-net rules but did not re-check the IP addresses that hostname resolved to. An attacker-controlled script could use a specially crafted domain name that passes the hostname check yet resolves to a denied IP,...

CVE-2026-49411

Summary (technical, grounded): CVE-2026-49411 affects Deno’s Node.js compatibility TCP path. Prior to v2.8.0, permission checks for deny-net were performed on the original hostname string before DNS resolution and not re-checked after resolution. This allowed a numeric IP alias (for example 21307...
