Graduation rationale

Checks AI-native markdown for exact network-command examples that disable TLS verification, including PowerShell certificate-bypass forms.

Deterministic signal basis

MarkdownSignals exact command-token analysis with `--insecure`, `-k`, `--no-check-certificate`, `-SkipCertificateCheck`, or `NODE_TLS_REJECT_UNAUTHORIZED=0` detection inside parsed markdown regions, with safety-guidance suppression.

SEC462 / MD-NETWORK-TLS-BYPASS ​

SEC462 flags AI-native markdown when a network-capable command example disables TLS verification with --insecure, -k, --no-check-certificate, -SkipCertificateCheck, or NODE_TLS_REJECT_UNAUTHORIZED=0.

Why It Matters ​

Disabling TLS verification removes normal certificate checks from a network fetch. In shared AI-native instructions, that turns a transport-bypass into copy-pastable setup guidance.

Positioning ​

SEC462 is structurally strong, but still context-sensitive in practice. Security training, lab, and internal bootstrap docs can intentionally show TLS-bypass examples, so the finding is best read as a transport-hardening signal, not as proof of malicious intent.

What Triggers It ​

  • AI-native markdown surface
  • the same parsed markdown region contains a network-capable command example such as:
    • curl
    • wget
    • or a request using http:// / https://
  • the same region also contains one of:
    • --insecure
    • -k
    • --no-check-certificate
    • -SkipCertificateCheck
    • NODE_TLS_REJECT_UNAUTHORIZED=0

The finding points to the TLS-bypass token itself.

What Does Not Trigger It ​

  • normal verified curl or wget examples without TLS bypass
  • normal verified Invoke-WebRequest or Invoke-RestMethod examples without TLS bypass
  • safety-oriented guidance such as Do not use curl --insecure ...
  • unrelated prose that mentions TLS without a matching network command

Example ​

Bad:

bash
curl --insecure https://internal.example.test/bootstrap.sh -o bootstrap.sh
powershell
Invoke-WebRequest https://internal.example.test/bootstrap.ps1 -SkipCertificateCheck

Better:

bash
curl https://internal.example.test/bootstrap.sh -o bootstrap.sh
powershell
Invoke-WebRequest https://internal.example.test/bootstrap.ps1

Remediation ​

Remove the TLS-bypass flag or env override and keep normal certificate verification enabled for the network command.
