    CVE-2026-4682

    Certain HP DeskJet All in One devices may be vulnerable to remote code execution caused by a buffer overflow when specially crafted Web Services for Devices (WSD) scan requests are improperly validated and handled by the MFP. WSD Scan is a Microsoft Windows–based network scanning protocol that allows a PC to discover scanners (and MFPs) on a network and send scan jobs to them without requiring vendor specific drivers or utilities.
