CVE-2026-42044

Description

A flaw was found in Axios, a widely used HTTP client. This vulnerability, known as a Prototype Pollution "Gadget" attack, allows a remote attacker to subtly alter JSON API responses. By manipulating a specific function, an attacker can selectively modify data within these responses. This could lead to significant security breaches, including unauthorized privilege escalation, fraudulent balance manipulation, or bypassing critical authorization checks.

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).
