CVE-2025-62718 — Axios has a NO_PROXY Hostname Normalization Bypass that Leads to SSRF

Affected: axios, Red Hat Ansible Automation Platform 2.5 for RHEL 8, Red Hat Ansible Automation Platform 2.5 for RHEL 9, Red Hat Streams for Apache Kafka 3.2.0, Red Hat Cluster Observability Operator 1.5.0, Red Hat multicluster engine for Kubernetes 2.6, Red Hat multicluster engine for Kubernetes 2.8, Red Hat Network Observability (NETOBSERV) 1.11.0, Red Hat Advanced Cluster Management for Kubernetes 2.14, Red Hat Advanced Cluster Security 4.9 and 53 more

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 NO_PROXY rules. Requests to loopback addresses like localhost. (with a trailing dot) or [::1] (IPv6 literal) skip NO_PROXY matching and go through the configured proxy. This goes against what developers expect and lets attackers force requests through a proxy, even if NO_PROXY is set up to protect loopback or internal services. This issue leads to the possibility of proxy bypass and SSRF vulnerabilities allowing attackers to reach sensitive loopback or internal services despite the configured protections. This vulnerability is fixed in 1.15.0 and 0.31.0.
