Worked on enhancing security and reliability for the EPA Snapshot module within the USEPA/webcms repository. Focused on backend development using PHP and Drupal, the work involved implementing robust URL normalization by stripping the host from meta refresh redirects and related anchor tags, ensuring that only relative paths are processed. This approach reduced the risk of open redirects and improved the consistency of URL handling throughout the module. Additional validations were added to explicitly check redirect safety, further strengthening the module’s reliability. The changes were delivered through two targeted commits, reflecting a methodical and security-conscious approach to backend engineering challenges.
