39-39: 🗄️ Data Integrity & IntegrationThe
PRandPR_ISSUEvalues can benullfor this event. However, the repository contains no n8n consumer or payload contract that shows either field selects the scan target. The claimed scan failure and proposed correction therefore remain conditional on an unobserved external implementation..github/dependabot.yml (1)

21-21: 🔒 Security & PrivacyDo not change the cache configuration for this concern.
Pull-request cache entries are scoped to the pull-request merge ref. Trusted pushes to
mainor tags cannot restore those entries. The explicitactions/cache@v6steps do not create the claimed cross-trust cache path.
package.jsonhas nopackageManagerordevEnginesfield, sosetup-node@v7does not enable automatic npm caching here. The proposedpackage-manager-cache: falsechange is unnecessary..github/workflows/n8n.yml-100-100 (1)

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.Keep the bearer token out of curl arguments.
This
-Hvalue placesN8N_BEARER_TOKENin curl's process arguments, where another process with access to the runner's process list can read it. Write the header to a temporary file with mode0600, pass it with-H @file, and remove the file on exit. curl supports headers from a file. (curl.se)Based on learnings, secret headers should not be embedded in curl command-line arguments.

actions/checkout steps in the workflow so repository-controlled pull request
commands do not receive checkout credentials; retain credentials only if a later
