CVE-2026-44488

Description

A flaw was found in Axios, a promise-based HTTP client. When using the fetch adapter, Axios did not properly enforce configured request and response size limits. This vulnerability allows a remote attacker, through a malicious or compromised server, or by supplying a large data URL, to send or receive oversized data bodies. This can lead to resource exhaustion in server-side applications, resulting in a Denial of Service (DoS).

Statement

Important: A denial of service flaw was found in Axios, a JavaScript HTTP client library. This issue arises when applications utilize the fetch adapter, as configured request and response size limits are not properly enforced. A remote attacker could exploit this by sending or receiving excessively large data bodies, leading to resource exhaustion and potential denial of service in affected server-side applications.

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).

Understanding the Weakness (CWE)

Availability

Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Resource Consumption (Other)

When allocating resources without limits, an attacker could prevent other systems, applications, or processes from accessing the same type of resource. It can be easy for an attacker to consume many resources by rapidly making many requests or causing larger resources to be used than is needed.
