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:4
Assessment Likely exploitable

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.

Threat Model Context

This is a Java service - vulnerabilities in servlets/controllers are remotely exploitable.

Changes

  • .github/dependabot.yml

Verification

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

}

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.
