AnalysisAIv1 – Jul 26, 2026

Remote code execution in HP DeskJet All-in-One printers via malformed WSD scan requests allows adjacent network attackers to fully compromise the device. A stack-based buffer overflow (CWE-121) in the MFP's processing of Web Services for Devices (WSD) scan jobs enables unauthenticated arbitrary code execution. No active exploitation or public proof-of-concept has been reported, and EPSS predicts low exploitation likelihood.

DescriptionCVE.org

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.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.

Attack Technique

Buffer Overflow HIGH

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.

Stack-based Buffer Overflow HIGH

A stack-based buffer overflow occurs when a program writes more data to a buffer located on the stack than it was allocated to hold.

Remote Code Execution CRITICAL

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
