Why It Matters ​

Embedding literal credentials directly in hook URLs or headers makes the committed hook itself a secret-bearing artifact. That creates both credential exposure risk and hard-to-rotate auth paths.

What Triggers ​

SEC205 applies to executable hook shell lines and triggers when literal auth material appears in:

  • URL userinfo
  • authorization headers
  • other direct auth-carrying network parameters

Examples that trigger:

sh
curl https://deploy-token@internal.test/bootstrap.sh -o /tmp/bootstrap.sh
curl -H 'Authorization: Bearer static-token-value' https://internal.test/bootstrap.sh

Example that stays clean:

sh
curl https://${DEPLOY_TOKEN}@internal.test/bootstrap.sh -o /tmp/bootstrap.sh

False Positives ​

This rule excludes dynamic placeholders and environment-backed auth references. It is aimed at committed literal credentials, not at all auth usage.

Remediation ​

Move embedded credentials out of URLs and headers into environment or provider-local auth configuration. There is no built-in fix because the correct credential source is deployment-specific.
