EXECUTIVE SUMMARY:
A vulnerability has been discovered in the widely used JavaScript library Axios, exposing millions of users to risks of Server-Side Request Forgery (SSRF) and credential leakage. The flaw, identified as CVE-2025-27152, is present in all versions of Axios up to and arises from improper handling of absolute URLs in requests. Even when a baseURL is set, Axios may send requests to absolute URLs, potentially bypassing security measures and allowing attackers to target internal resources or leak sensitive information, including API keys and credentials. This vulnerability could be exploited by attackers to compromise internal networks and access unintended services, making the issue particularly severe given Axios’s extensive use in web applications. It is advised to update to the version immediately and implement additional safeguards, such as validating path parameters, to mitigate the risks. This could allow malicious actors to manipulate request destinations, leading to unauthorized data access or unintended API interactions. Furthermore, it could exploit this flaw to perform lateral movement within a network, escalating their access to more systems.[/subscribe_to_unlock_form]
