Remote Code Execution and Elevation of Privilege Vulnerability in HP LaserJet Printers

CVE-2025-26506

What is CVE-2025-26506?

CVE-2025-26506 is a vulnerability found in specific models of HP LaserJet printers, including the LaserJet Pro, LaserJet Enterprise, and LaserJet Managed printers. This vulnerability allows for remote code execution and elevation of privilege when processing PostScript print jobs. Such a flaw can severely compromise an organization’s security posture, as it may enable unauthorized actors to execute arbitrary code on the printer, potentially leading to data leaks or manipulation and undermining the integrity of sensitive print jobs.

Technical Details

The vulnerability arises from the way the printers handle PostScript print jobs, which are commonly used for document representation and printing. Attackers could take advantage of this flaw by sending specially crafted PostScript files to the affected printers. Upon processing these files, the printers may inadvertently execute malicious code, leading to unauthorized access or control over the device. This scenario creates a significant risk within any network that utilizes these printers, particularly in enterprise environments where sensitive data is often printed.

Potential Impact of CVE-2025-26506

1. Unauthorized Access: Exploiting this vulnerability could allow an attacker to gain unauthorized access to the printer’s system, potentially leading to further network infiltration and manipulation of connected devices.

2. Data Leakage: If attackers achieve control through this vulnerability, they might access sensitive documents processed by the printer, resulting in data breaches that can have legal and reputational consequences for the organization.

3. Operational Disruption: The introduction of malicious code through this flaw could disrupt normal printing operations, leading to business downtime and potential loss of productivity as IT teams work to mitigate the effects and restore normal functionality.
