ecosystem impact- 17 npm packages depend on axios (14 direct, 3 indirect)
Ecosystem-wide dependent count for version 1.7.0.
DescriptionCVE.org
axios versions 1.7.0 before 1.18.0 fail to enforce maxBodyLength for WHATWG ReadableStream request bodies in the fetch adapter when Content-Length cannot be determined. Attackers can supply unknown-length stream data to bypass upload size limits and cause uncontrolled network egress or resource exhaustion.
AnalysisAI
The fetch adapter in axios 1.7.0 through 1.17.x silently skips the maxBodyLength enforcement when a WHATWG ReadableStream body has no determinable Content-Length, allowing attacker-supplied stream data to bypass configured upload size limits. Applications that proxy or relay untrusted stream data via axios with the fetch adapter and rely solely on maxBodyLength as the size guard are exposed to uncontrolled outbound egress and potential exhaustion of upstream API quotas or bandwidth. No public exploit has been identified at time of analysis; CVSS 4.0 scores this at 6.3 with limited availability impact (VA:L) and an attack prerequisite (AT:P) reflecting the specific conditions required.
Technical ContextAI
The root cause is CWE-770 (Allocation of Resources Without Limits or Throttling), traced to a missing code branch in lib/adapters/fetch.js. The getBodyLength() function handles Blob, spec-compliant FormData, ArrayBuffer, URLSearchParams, and strings, but has no branch for WHATWG ReadableStream objects. Consequently, resolveBodyLength() returns undefined for live streams, and the maxBodyLength guard - which only fires when the resolved outbound length is a finite number exceeding the configured limit - is silently bypassed. The onUploadProgress wrapper (trackStream()) also does not enforce the cap; it only reports byte progress. The HTTP adapter's stream upload path in Node.js is entirely separate and is not affected. Affected product per CPE: cpe:2.3:a:axios:axios:*:*:*:*:*:*:*:* covering npm versions >= 1.7.0 and < 1.18.0 - versions before 1.7.0 predate the fetch adapter entirely and are not affected.
RemediationAI
Upgrade to axios 1.18.0, which resolves the issue by adding a ReadableStream branch to getBodyLength() so that maxBodyLength is enforced for stream bodies; the fix is in commit 32fc489632377d214db55bfa4e2c48486a7d7ce2 (merged via PR #11000). Advisory: https://github.com/axios/axios/security/advisories/GHSA-jqh4-m9w3-8hp9. If upgrading is not immediately possible, the most direct compensating control is to explicitly configure axios to use the HTTP adapter (adapter: 'http') in Node.js environments, which eliminates the vulnerable code path entirely; note this will break deployments on edge runtimes where the fetch adapter is required. As a defense-in-depth measure independent of axios version, implement request body size limits at the HTTP server or reverse-proxy layer - for example, nginx client_max_body_size or Node.js http.maxHeaderSize and equivalent body limits - so that maxBodyLength is never the sole enforcement mechanism for untrusted stream uploads. Trade-off: upstream proxy limits may reject legitimate large uploads that would otherwise be handled by application logic.
