Addressing the Polyfill.io Vulnerability in Drupal: Security Measures and Solutions
Max Pogonowski's recent blog post on Sitback discusses a critical vulnerability in the Drupal community involving the polyfill.io service. After being sold to new owners, the service began injecting malware into its scripts, constituting a supply-chain attack. To mitigate this risk, Max advises Drupal site owners to update all modules or use Cloudflare, which has implemented automatic protections.
The post highlights the importance of relying on trusted repositories like git.drupalcode.org for Drupal and warns against using third-party services like polyfill.io. Max also introduces the Frontend Bundler Initiative, which aims to compile contributed modules into libraries for Drupal projects, thereby reducing dependency on external CDNs and enhancing security against supply-chain attacks.
