Network-reachable and unauthenticated (AV:N/PR:N), but requires fetch adapter + maxRedirects:0 + attacker-influenced redirect (AC:H); the bypass reaches other systems so S:C with modest, situational C/I impact.

Ecosystem-wide dependent count for version 1.17.0.

DescriptionCVE.org

Axios is a promise-based HTTP client for the browser and Node.js. From 1.17.0 until 1.20.0, the fetch adapter bypasses the maxRedirects: 0 redirect policy. An Axios request uses the fetch adapter with maxRedirects set to zero and receives a redirect response. The underlying fetch implementation follows the redirect instead of returning the redirect response unchanged. The redirected request can access internal responses or reach state-changing internal endpoints despite redirects being disabled. This issue is fixed in version 1.20.0.

AnalysisAI

Redirect-policy bypass in Axios 1.17.0 up to (but not including) 1.20.0 causes the fetch adapter to follow HTTP 3xx redirects even when the application explicitly sets maxRedirects: 0, so a redirect-blocking control that developers rely on as a security boundary is silently ignored. The flaw is a confused-deputy issue (CWE-441): an attacker positioned to control a redirect response from a server the application calls can push the request to internal responses or state-changing internal endpoints that should have been unreachable. …

Vulnerability AssessmentAI

Exploitation Requires the application to (1) use the axios fetch adapter (not the default http/xhr adapters), (2) explicitly set maxRedirects:0 and rely on it as a redirect-blocking security control, and (3) issue a request to a server that returns a 3xx redirect whose Location the attacker can influence toward an internal or state-changing endpoint. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The provided CVSS 4.0 vector (CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N, base 7.0) is internally coherent for a confused-deputy flaw (CWE-441): no impact on the axios host itself (VC/VI/VA:N) but high confidentiality/integrity impact on SUBSEQUENT systems (SC:H/SI:H) - i.e., the internal endpoints reachable once the maxRedirects:0 control is bypassed. … 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 (https://github.com/axios/axios/releases/tag/v1.20.0), which implements maxRedirects: 0 via manual redirect handling in the fetch adapter as documented in the project changelog; the corresponding changes are in PR https://github.com/axios/axios/pull/11141 and commit d19040bda7a8be2f82c3c6e1a5bc03917daee39a. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, inventory all applications and services using Axios and identify any running versions from 1.17.0 up to, but not including, 1.20.0 that use the fetch adapter and explicitly set maxRedirects: 0 as a security control; where found, immediately disable the fetch adapter in favor of the default http or xhr adapter, or move redirect-blocking enforcement to an upstream proxy/WAF/egress gateway, and add temporary logging for any 3xx responses to sensitive or internal destinations. …
