CVE-2026-42041
Description
A flaw was found in Axios, a promise-based HTTP client. This vulnerability, a Prototype Pollution "Gadget" attack, allows an attacker to manipulate the Object.prototype.validateStatus property. By polluting this property, all HTTP error responses (such as 401, 403, or 500) are silently treated as successful responses. This can lead to a complete bypass of application-level authentication and error handling, potentially granting unauthorized access.
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).
