CVE-2026-62985 · request-filtering-agent: Synchronous throw from createConnection() for literal private-IP hosts bypasses req.on('error'), crashing the Node.js process
This page contains facts from public vulnerability sources. Check the original advisory before updating.
request-filtering-agent is an http(s).Agent implementation that blocks requests to Private/Reserved IP addresses. Prior to 3.2.1, RequestFilteringHttpAgent and RequestFilteringHttpsAgent synchronously threw from createConnection when rejecting a literal private-IP host such as 169.254.169.254 or 127.0.0.1. Because Node.js http.request and http.get expect connection failures to be delivered asynchronously, the throw bypassed req.on('error') and became an uncaught exception that could terminate the application process. Hostnames resolved through the asynchronous lookup path were not affected by this error-delivery asymmetry. This issue is fixed in version 3.2.1.
