Axios maintainers have disclosed high-severity security vulnerabilities that expose users to server-side request forgery (SSRF). These flaws, identified in the HTTP/2 request path, allow attackers to bypass critical proxy and DNS security controls.
Why it matters
The disclosure highlights a significant security risk for applications relying on the widely used Axios HTTP library to handle internal service requests. By enabling unauthorized access to internal resources, the flaw threatens the integrity of service-to-service communication.
The critical vulnerability, tracked as GHSA-3pq3-5fj3-cg6v, specifically impacts the Axios HTTP/2 request path. This exposure is significantly more severe than standard request handling due to its capacity to bypass enforced proxy and DNS restrictions.
The players
Axios
An open-source, promise-based HTTP client for the browser and Node.js widely used for handling asynchronous network requests.
The details
The vulnerability stems from how the HTTP/2 adapter establishes sessions, which fails to properly validate the target destination against security policies. Server-side request forgery (SSRF) — a security exploit where an attacker induces a server-side application to make HTTP requests to an arbitrary domain — is enabled when the library ignores proxy or DNS controls. This allows the library to reach internal services that would otherwise be shielded from external network traffic.
Timeline

The Tech Race
The Axios HTTP client library serves as a foundational component for countless modern web applications. This security disclosure forces a widespread re-evaluation of how HTTP/2 session management is implemented across the broader developer ecosystem.
Developers should audit their implementations that utilize the Axios HTTP/2 adapter to ensure they are protected against unauthorized internal requests. Organizations should review dependency management policies to determine if updates are required to mitigate the risk posed by GHSA-3pq3-5fj3-cg6v.
The takeaway
The security of internal service architecture depends on the robust handling of requests by third-party libraries like Axios. Developers should watch for subsequent maintenance releases that address the GHSA-3pq3-5fj3-cg6v identifier.
