CVE-2026-44494
Description
A flaw was found in Axios. This vulnerability, a Prototype Pollution "Gadget" attack, allows an attacker to escalate any existing Object.prototype pollution in an application's dependency tree into a full Man-in-the-Middle (MITM) attack. This enables the attacker to intercept, read, and modify all HTTP traffic, including sensitive authentication credentials. The flaw occurs because the config.proxy setting is susceptible to prototype pollution, allowing an attacker to inject a malicious proxy server.
Statement
This Important flaw in the Axios library allows an attacker to escalate existing prototype pollution vulnerabilities within an application's dependency tree into a full Man-in-the-Middle (MITM) attack. By injecting a malicious proxy configuration into the Object.prototype, an attacker can intercept, read, and modify all HTTP traffic, including sensitive authentication credentials, without direct user interaction. This poses a significant risk to data confidentiality and integrity in Red Hat products that utilize the Axios library.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
