CVE-2025-54371: High severity npm/axios vulnerability

Withdrawn Advisory This advisory has been withdrawn because users of Axios 1.10.0 have the flexibility to use a patched version of form-data, the software in which the vulnerability originates, without upgrading Axios to address GHSA-fjxv-7rqg-78g4.

Original Description A critical vulnerability exists in the form-data package used by axios@1.10.0. The issue allows an attacker to predict multipart boundary values generated using Math.random(), opening the door to HTTP parameter pollution or injection attacks.

This was submitted in issue #6969 and addressed in pull request #6970.

Details The vulnerable package form-data@4.0.0 is used by axios@1.10.0 as a transitive dependency. It uses non-secure, deterministic randomness (Math.random()) to generate multipart boundary strings.

This flaw is tracked under Snyk Advisory SNYK-JS-FORMDATA-10841150 and CVE-2025-7783.

Affected form-data versions: - <2.5.4 - >=3.0.0 <3.0.4 - >=4.0.0 <4.0.4

Since axios@1.10.0 pulls in form-data@4.0.0, it is exposed to this issue.

PoC 1. Install Axios: - npm install axios@1.10.0 2.Run snyk test: Tested 104 dependencies for known issues, found 1 issue, 1 vulnerable path.

✗ Predictable Value Range from Previous Values [Critical Severity] in form-data@4.0.0 via axios@1.10.0 > form-data@4.0.0

3. Trigger a multipart/form-data request. Observe the boundary header uses predictable random values, which could be exploited in a targeted environment.

Impact

- Vulnerability Type: Predictable Value / HTTP Parameter Pollution - Risk: Critical (CVSS 9.4) - Impacted Users: Any application using axios@1.10.0 to submit multipart form-data

This could potentially allow attackers to: - Interfere with multipart request parsing - Inject unintended parameters - Exploit backend deserialization logic depending on content boundaries
