AC:H and S:C because exploitation needs non-default httpVersion:2 plus a security-relevant proxy/DNS policy, and the bypass affects a separate network boundary; impact limited to L (control bypass, no direct system compromise).

  • 25 npm packages depend on axios (15 direct, 10 indirect)

Ecosystem-wide dependent count for version 1.13.0.

DescriptionCVE.org

Axios is a promise-based HTTP client for the browser and Node.js. From 1.13.0 until 1.20.0, Axios HTTP/2 request setup does not consistently apply proxy settings and caller-supplied DNS lookup policy. An HTTPS request uses httpVersion: 2 with explicit config.proxy or environment-derived proxy settings, or relies on caller-supplied config.lookup DNS policy. The HTTP/2 path can connect without the configured proxy behavior or without applying the caller-supplied config.lookup policy before http2.connect(). Requests can bypass the intended proxy route or the caller-supplied DNS resolution policy. This issue is fixed in version 1.20.0.

AnalysisAI

Axios versions 1.13.0 through 1.19.x on Node.js can silently bypass a configured HTTP(S) proxy or a caller-supplied DNS lookup policy for requests that opt into HTTP/2, because the HTTP/2 adapter calls http2.connect() without consistently applying config.proxy, environment-derived proxy settings, or config.lookup before the connection is established. This is a defense-in-depth control bypass (CWE-918, SSRF-adjacent): confidentiality and integrity impacts fall on the systems the bypassed egress or DNS control was meant to protect, not on the local vulnerable host, and exploitation is gated by non-default configuration - the application must explicitly set httpVersion: 2 and must actually depend on the proxy or lookup policy as a security boundary. …

Vulnerability AssessmentAI

Exploitation Requires an application that (1) explicitly opts into HTTP/2 by setting Axios httpVersion:2 (not the default), and (2) depends on either config.proxy, environment-derived proxy settings, or a caller-supplied config.lookup DNS policy as an actual security control (egress inspection/filtering or DNS-rebinding pinning). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a defense-in-depth control-bypass (CWE-918 SSRF-adjacent) in Axios, one of the most widely deployed npm HTTP clients, but real-world risk is moderate and gated by non-default configuration. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Vendor-released patch: upgrade to axios 1.20.0, which applies custom config.lookup functions on HTTP/2 connections and stops silently ignoring proxy intent (references: https://github.com/axios/axios/security/advisories/GHSA-3pq3-5fj3-cg6v, https://github.com/axios/axios/releases/tag/v1.20.0, PR https://github.com/axios/axios/pull/11141, commit https://github.com/axios/axios/commit/d19040bda7a8be2f82c3c6e1a5bc03917daee39a). … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, inventory all Node.js applications for Axios versions 1.13.0 through 1.19.x and identify any callers that set httpVersion: 2 or otherwise opt into HTTP/2 while relying on a configured proxy, environment-derived proxy settings, or a caller-supplied DNS lookup policy as a security boundary; where found, immediately disable HTTP/2 by removing httpVersion: 2 or forcing HTTP/1.1, and reinforce egress filtering and DNS controls at the network or platform layer so Axios cannot bypass them. …
