GHSA-V228-72C7-FX8J open-websearch has SSRF in `fetchWebContent` MCP tool: bracketed IPv6 literals and non-resolving hostname check bypass `isPrivateOrLocalHostname`

Summary src/utils/urlSafety.ts exposes isPublicHttpUrl / assertPublicHttpUrl, used to gate the MCP fetchWebContent tool against private-network targets. The check has two defects that together allow non-blind SSRF with the response body returned to the caller: 1. Bracketed IPv6 literals are never...

GHSA-J4RJ-2JR5-M439 ssrfcheck Vulnerable to Server-Side Request Forgery (SSRF) and Incomplete List of Disallowed Inputs

Summary ssrfcheck v1.3.0 latest fails to block Server-Side Request Forgery attacks when the target private IP address is encoded as an IPv4-mapped IPv6 address e.g. http://::ffff:127.0.0.1/. The WHATWG URL parser built into Node.js silently normalizes the IPv4 notation inside the brackets to...

Server-side Request Forgery (SSRF)
