axios-0.21.4.tgz: 3 Vulnerabilities (Highest Severity is: 7.5)

Axios is a popular promise-based HTTP client for the browser and Node.js. It provides a simple and intuitive way to make HTTP requests, making it a widely-used library in the JavaScript ecosystem. However, like any other library, Axios is not immune to vulnerabilities. In this article, we will discuss three vulnerabilities found in Axios version 0.21.4.tgz, including their severity, impact, and suggested fixes.

WS-2023-0439

CVE	Severity	CVSS	Dependency	Type	Fixed in (axios version)	Remediation Possible
WS-2023-0439	High	7.5	axios-0.21.4.tgz	Direct	1.6.3	❌

Vulnerability Details

Axios is vulnerable to Regular Expression Denial of Service (ReDoS). When a manipulated string is provided as input to the format method, the regular expression exhibits a time complexity of O(n^2). Server becomes unable to provide normal service due to the excessive cost and time wasted in processing vulnerable regular expressions.

CVE-2025-27152

CVE	Severity	CVSS	Dependency	Type	Fixed in (axios version)	Remediation Possible
CVE-2025-27152	High	7.5	axios-0.21.4.tgz	Direct	1.8.2	❌

Vulnerability Details

axios is a promise based HTTP client for the browser and node.js. The issue occurs when passing absolute URLs rather than protocol-relative URLs to axios. Even if ⁠baseURL is set, axios sends the request to the specified absolute URL, potentially causing SSRF and credential leakage. This issue impacts both server-side and client-side usage of axios. This issue is fixed in 1.8.2.
