Pull request overview

This is a Snyk-generated security upgrade PR that updates the Padrino gem from version 0.12.4 to 0.12.9 in the example application. The upgrade aims to address two medium-severity vulnerabilities in Rack: Directory Listing exposure (SNYK-RUBY-RACK-15307669) and Cross-site Scripting (SNYK-RUBY-RACK-15307670). However, the automated process failed to update the Gemfile.lock file, requiring manual intervention before the security fixes can take effect.

Changes:

• Updated padrino version constraint from '0.12.4' to '0.12.9' in example/Gemfile
• Gemfile.lock requires manual update (not included in this PR)

The Gemfile.lock file was not updated as part of this PR (as noted in the PR description warning). This means the dependency upgrade will not take effect until the Gemfile.lock is regenerated. The vulnerabilities in Rack (versions 1.5.2 currently in the lockfile) will remain unpatched until you run bundle update padrino in the example directory and commit the updated Gemfile.lock.

Note that while Padrino 0.12.9 exists and is a valid version, it's quite old (from 2016). Consider upgrading to a more recent version of Padrino (0.15.x series) to get better security patches and bug fixes, though this may require more extensive testing for breaking changes.

Suggested change

	gem 'padrino', '0.12.9'
