CVE-2026-101909

Description

A flaw was found in axios. In applications affected by prototype pollution, where an attacker can modify base JavaScript object properties, axios processes inherited options during form data serialization without verifying property ownership. An attacker can leverage this behavior to trigger a Denial of Service (DoS) by causing requests to fail, alter outgoing serialized request data, or potentially execute arbitrary code if function injection is possible.

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.
