Name of the Vulnerable Software and Affected Versions Link Preview JS versions prior to 4.0.1 Description The library fails to check for IPv6 loopback attacks and is susceptible to DNS attacks where an address can be resolved into an internal IP. These issues may lead to internal data leaks...

axios: Axios: Server-Side Request Forgery and proxy bypass due to improper hostname normalization

A flaw was found in Axios, a promise-based HTTP client. This vulnerability occurs because Axios does not correctly handle hostname normalization when evaluating NOPROXY rules. An attacker can exploit this by crafting requests to loopback addresses e.g., localhost. or ::1 which bypass the NOPROXY...

GHSA-R6XH-PQHR-V4XH OpenClaw: MCP loopback owner context is derived from server-issued bearer tokens

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...

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...
