    Title
    PHPOffice PHPPresentation through 1.2.0 Deserialization via Reader\Serialized::load
    Summary
    PHPOffice PHPPresentation through 1.2.0 contains an insecure deserialization vulnerability that allows attackers to instantiate arbitrary PHP objects by supplying a crafted presentation file. Attackers can upload a ZIP containing PhpPresentation.xml that IOFactory::load passes to unserialize(), enabling gadget-chain code execution, file writes, or denial of service.
