Security Gap Exposed: Project Lacks Scheduled Vulnerability Scans, Risking Undetected CVEs

A critical security oversight has been identified in a software project's continuous integration pipeline. While the `govulncheck` tool runs on every code push or pull request, the system lacks any scheduled, automated scanning. This creates a dangerous blind spot: if a new Common Vulnerability and Exposure (CVE) is disclosed in a transitive dependency and no developer commits new code, the vulnerability can persist undetected indefinitely, exposing the project to potential exploitation.

The proposed fix is a new GitHub Actions workflow file, `.github/workflows/security-scan.yml`. This workflow is designed to execute on a scheduled cron job every Monday at 06:00 UTC, with a manual trigger option via `workflow_dispatch`. Its core function is to run `govulncheck` comprehensively across all five of the project's modules. Crucially, the workflow is configured to automatically open a new GitHub issue if the scan detects any vulnerabilities, requiring specific write permissions for the issues scope.

This missing layer of passive defense represents a significant operational risk. The absence of scheduled scans means security posture is entirely reactive to developer activity, not proactive against the constant stream of newly published vulnerabilities. Implementing this workflow is a foundational step to close this gap, ensuring newly disclosed threats in dependencies are flagged weekly, regardless of whether the codebase is actively being modified. The acceptance criteria mandate strict version pinning of all actions and specific handling for non-zero exit codes from the scanner to ensure reliable, automated alerting.
