What the CVE records say

CVE-2026-3783 — When an OAuth2 bearer token is used for an HTTP(S) transfer, and that transfer performs a redirect to a second URL, curl could leak that token to the second hostname under some circumstances. If the hostname that the first request is redirected to has information in the used .netrc file, with either of the `machine` or `default` keywords, curl would pass on the bearer token set for the first host also to the second one.

Impact

Successful exploitation of this vulnerability could lead to disclosure of sensitive information.

What to do

  1. Check the affected products listed above against the official advisory's affected-versions table — that is where the exact ONTAP 9 release, ONTAP tool, or management product versions are named.
  2. If affected and a fixed release exists, plan the upgrade — see the ONTAP upgrade runbook.
  3. If exploitation is listed as "active", treat remediation as urgent and review exposure (management LIFs, ONTAP S3, SnapMirror endpoints).
  4. Harden in parallel: security hardening baseline and ransomware protection on ONTAP.
