High severity with no evidence of exploitation so far.
What to do
- Check which version of Apache DolphinScheduler you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on lists.apache.org for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
Because the HttpUtils class did not verify certificates, an attacker that could perform a Man-in-the-Middle (MITM) attack on outgoing https connections could impersonate the server. This issue affects Apache DolphinScheduler: before 3.2.0. Users are recommended to upgrade to version 3.2.1, which fixes the issue.

The underlying weakness: Improper Certificate Validation
The product does not validate, or incorrectly validates, a certificate.
How developers prevent this class of flaw
- Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
- If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
