Description

Axios fetch adapter requests can be altered by inherited properties on fetchOptions. The adapter resolves method, headers, body, signal, and credentials into resolvedOptions, creates a Request, and then calls fetch(request, fetchOptions) instead of fetch(request, resolvedOptions).

Recommendation

Update the axios package to the latest compatible version. Followings are version details:

  • Affected version(s): >= 1.7.0, < 1.20.0
  • Patched version(s): 1.20.0
