Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
axios versions 0.31.1 before 0.33.0 and 1.15.1 before 1.18.0 contain an incomplete depth-limit bypass in toFormData.js when serializing objects with top-level keys ending in '{}'. Attackers who control object keys and nested values passed to axios form or parameter serialization can trigger a RangeError from JSON.stringify, causing denial of service in the affected request path.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Recommended fix Moderate confidence

axios 0.33.0 or later

  1. 1. Identify all projects and dependencies that use axios library
  2. 2. Run 'npm list axios' or check package.json to confirm current axios version in each project
  3. 3. If axios version is below 0.33.0, upgrade by running: npm install axios@^0.33.0 or npm update axios
  4. 4. For yarn projects, run: yarn upgrade axios@^0.33.0
  5. 5. For pnpm projects, run: pnpm update axios@^0.33.0
  6. 6. After upgrade, test that form serialization functionality works correctly in your application
  7. 7. Rebuild and redeploy applications that had the vulnerable axios version
Caveat Minor: Review axios changelog for any breaking changes between your current version and 0.33.0; the toFormData API may have changed
