CVE-2026-44490
Description
A flaw was found in Axios, a promise-based HTTP client. This vulnerability, known as prototype pollution, allows an upstream dependency to modify the fundamental behavior of JavaScript objects. When this occurs, Axios can unknowingly incorporate these altered values, leading to two potential consequences. This can result in sensitive information being inadvertently included in network requests, or cause application instability and crashes, leading to a denial of service.
Statement
This Moderate impact flaw in Axios, a JavaScript HTTP client, affects Red Hat products that integrate vulnerable versions and are susceptible to prototype pollution from other dependencies. Exploitation could lead to sensitive information disclosure in network requests or result in application instability and denial of service, particularly in environments where Object.prototype is modified by other components.
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).
The following CVSS metrics and score provided are preliminary and subject to review.
