Assigner: hp
Reserved: 23.03.2026 Published: 15.04.2026 Updated: 15.04.2026

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.
