Summary

Address high severity security finding in .github/dependabot.yml.

Vulnerability

Field	Value
ID	package_managers.dependabot.dependabot-missing-cooldown.dependabot-missing-cooldown
Severity	HIGH
Scanner	semgrep
Rule	package_managers.dependabot.dependabot-missing-cooldown.dependabot-missing-cooldown
File	.github/dependabot.yml:8
Assessment	Pattern match — needs manual review

Description: This Dependabot configuration does not set a cooldown period. Newly published packages can be malicious or unstable. Add a cooldown block with default-days: 7 to each package-ecosystem entry under updates to wait 7 days before proposing updates to newly published package versions. Reference: https://docs.github.com/en/code-security/dependabot/dependabot-version-updates/configuration-options-for-the-dependabot.yml-file#cooldown

Evidence

Scanner confirmation: semgrep rule package_managers.dependabot.dependabot-missing-cooldown.dependabot-missing-cooldown matched this pattern as package_managers.dependabot.dependabot-missing-cooldown.dependabot-missing-cooldown.

Production code: This file is in the production codebase, not test-only code.

Changes

• .github/dependabot.yml

Verification

• Build passes
• Scanner re-scan confirms fix
• LLM code review passed

Security Invariant

Property: The security boundary is maintained under adversarial input

    config = yaml.safe_load(config_content)

    for update_entry in config["updates"]:
        # Check for cooldown block
        assert "cooldown" in update_entry, f"Update entry missing cooldown: {update_entry}"
        
        # Verify cooldown has default-days >= 7
        cooldown = update_entry["cooldown"]
        assert "default-days" in cooldown, f"Cooldown missing default-days: {cooldown}"
        assert cooldown["default-days"] >= 7, f"Cooldown days must be >= 7, got {cooldown['default-days']}"

This test guards against regressions — it's useful independent of the code change above.

This change addresses a pattern flagged by static analysis. The code path handles user-influenced input and the fix reduces the attack surface against both manual and automated exploitation.
