Grav is a file-based Web platform. Prior to 2.0.1, Grav ZipArchiver::extract() in system/src/Grav/Common/Filesystem/ZipArchiver.php passes archives to ZipArchive::extractTo() without enforcing the system.gpm.archive uncompressed-size, file-count, or nesting-depth limits. Code using Archiver::create('zip') to extract an attacker-controlled archive can exhaust disk space or inodes and make the site unavailable. This issue is fixed in version 2.0.1.
