CVE-2026-42035

Description

A flaw was found in Axios, a software library for making network requests. A remote attacker can exploit a prototype pollution vulnerability to inject arbitrary HTTP headers into outgoing requests. This occurs when the application's core object definitions are manipulated, causing Axios to misinterpret data and include attacker-controlled headers in network communications. This could lead to unauthorized actions or data manipulation.

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).
