Summary

CVE-2025-26507 is a medium-severity Stack-based Buffer Overflow (CWE-121) vulnerability in Hp Futuresmart 5. Its CVSS base score is 6.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 14.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-2 (Flaw Remediation) and SC-7 (Boundary Protection).

Deeper analysis

Certain HP LaserJet Pro, Enterprise, and Managed Printers are affected by CVE-2025-26507, a vulnerability that can lead to remote code execution and elevation of privilege during PostScript print job processing. The issue is tracked under CWE-121 and carries a CVSS 4.0 score of 6.3 with a network attack vector, high attack complexity, and no required privileges or user interaction.

An unauthenticated remote attacker can submit a specially crafted PostScript job to an exposed printer, potentially executing arbitrary code and gaining elevated privileges on the device. The attack requires the printer to accept and process PostScript input over the network.

HP has published mitigation guidance in security bulletin HPSBPI04007, available at the referenced support document. The EPSS score rose from a low baseline to a peak of 0.0609 before receding to the current value of 0.0245, indicating a temporary increase in observed exploitation interest after disclosure.

Related Threats

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1210 Exploitation of Remote Services Lateral Movement
Adversaries may exploit remote services to gain unauthorized access to internal systems once inside of a network.
T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
Why these techniques?

The CVE describes unauthenticated network-accessible RCE via malicious PostScript print job exploiting a buffer overflow, directly enabling exploitation of public-facing/remote services for initial access and privilege escalation on the device.
