Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A potential security vulnerability has been identified in the HP Linux Imaging and Printing Software. This potential vulnerability may allow escalation of privileges and/or arbitrary code execution via operating system command injection.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A command injection vulnerability in HP Linux Imaging and Printing Software allows attackers to inject malicious OS commands, potentially achieving privilege escalation to root or executing arbitrary code with elevated permissions.

MitigationImplement strict input validation and sanitization for all user-supplied data passed to system calls; use parameterized commands or avoid shell execution entirely where possible.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify if HPLIP is installed
    Run 'dpkg -l hplip' (Debian/Ubuntu) or 'rpm -qa | grep -i hplip' (RHEL/CentOS) to check for the hplip package
    Affected if The package is installed and the version shown is below 3.26.4
  2. Get the exact HPLIP version
    Run 'hp-version' (if available) or check the package version with 'dpkg -s hplip | grep Version' / 'rpm -qi hplip | grep Version'
    Affected if The installed version is lower than 3.26.4
  3. Check if HPLIP services are running
    Run 'systemctl list-units | grep -i hp' or 'ps aux | grep -i hplip' to see if any HPLIP daemon processes are active
    Affected if HPLIP services are running on an unpatched version below 3.26.4
  4. Verify user access to HPLIP utilities
    Check which users have access to hplip tools by reviewing '/usr/bin/hp*' permissions with 'ls -la /usr/bin/hp*' and checking for SUID bits
    Affected if Any local user can execute HPLIP utilities and the installed version is below 3.26.4
  5. Review HPLIP configuration files
    Examine configuration files in /etc/hp/ or ~/.hp/ directories for unusual settings, especially those involving external command execution
    Affected if Configuration allows external command invocation and the version is below 3.26.4

A system is affected if HP Linux Imaging and Printing Software is installed with a version lower than 3.26.4 and any local user can access HPLIP utilities.

Implement strict input validation and sanitization for all user-supplied data passed to system calls; use parameterized commands or avoid shell execution entirely where possible.

Recommended fix Moderate confidence

Linux Imaging and Printing 3.26.4 or later

  1. 1. Identify the current version of HP Linux Imaging and Printing installed on the system
  2. 2. If the installed version is below 3.26.4, plan for the upgrade
  3. 3. Obtain the updated HP Linux Imaging and Printing package version 3.26.4 or later from the official HP support website (support.hp.com)
  4. 4. Stop any printing services or processes using the HP Imaging software before upgrading
  5. 5. Install the updated package using the appropriate package manager for your distribution (e.g., dpkg, rpm, or yum/dnf)
  6. 6. Restart the printing services that were stopped before the upgrade
  7. 7. Verify the new version is installed correctly by checking the version number
