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.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
