Security Bulletin: Axios NO_PROXY Bypass via Improper Hostname Normalization Leads to SSRF

Summary Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.0 and 0.31.0, Axios does not correctly handle hostname normalization when checking NOPROXY rules. Requests to loopback addresses like localhost. with a trailing dot or ::1 IPv6 literal skip NOPROXY matching an...

Name of the Vulnerable Software and Affected Versions OpenClaw versions prior to 2026.4.22 Description OpenClaw derives loopback MCP owner context from spoofable server-issued bearer tokens in request headers. Non-owner loopback clients can bypass owner-gated operations by manipulating the...

CVE-2026-7422

Insufficient packet validation in FreeRTOS-Plus-TCP before V4.2.6 and V4.4.1 allows an adjacent network actor to bypass all checksum and minimum-size validation by spoofing the Ethernet source MAC address to match one of the device's own registered endpoints, because the loopback detection...

DNS rebinding vulnerability in rmcp Streamable HTTP server transport

Prior to version 1.4.0, the rmcp crate's Streamable HTTP server transport did not validate the incoming Host header. This allowed a malicious public website, via a DNS rebinding attack, to send requests to an MCP server running on the victim's loopback or private-network interface. An attacker wh...

CVE-2026-42038

A flaw was found in Axios, a software library used for making web requests. This vulnerability allows an attacker to bypass the noproxy configuration, which is designed to prevent certain internal network requests from being sent through an external proxy. Specifically, when noproxy=localhost is...

CVE-2026-41403

OpenClaw before 2026.3.31 misclassifies proxied remote requests as loopback connections in the diffs viewer when allowRemoteViewer is disabled, allowing unauthorized access. Attackers can bypass access controls by sending proxied requests that are incorrectly identified as local loopback traffic,...

Proxy Bypass

Axios is vulnerable to Proxy Bypass. The vulnerability is due to incomplete NOPROXY handling for loopback addresses, where requests to the 127.0.0.0/8 range excluding 127.0.0.1 bypass proxy restrictions, allowing attackers to access internal or local services despite configured protections...
