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
During installation with certain driver software or application packages an arbitrary code execution could occur.

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 · low confidence
Developing — this CVE was published recently and its authoritative NVD entry is still being established, so we're holding a technical summary until the source data settles rather than publish something unreliable. Re-checking after 2026-08-01.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

Upgrade to firmware version 61.111.01.9108 or later for Cm4540 Mfp; 11.0.19232.882 or later for M880z/M880zm; 52.1.4899 or later for M455; 14.0.19241.351 or later for M552; 14.0.19232.485 or later for M553; 10.0.16007.5 or later for M651

  1. Obtain the firmware update from HP Support: Visit support.hp.com and search for your specific printer model (e.g., Color Laserjet Cm4540 Mfp)
  2. Download the firmware file corresponding to your printer model
  3. Access the printer's embedded web server by entering the printer's IP address in a web browser
  4. Navigate to the 'General' or ' firmware' tab in the web interface
  5. Locate the firmware update section and select the downloaded firmware file
  6. Click 'Apply' or 'Update' to initiate the firmware upgrade
  7. Wait for the upgrade process to complete - do not power off the printer during the update
  8. After the update, verify the firmware version matches or exceeds the fixed version for your model
Caveat Firmware updates on HP printers are generally low-risk but may reset some custom settings; backup printer configuration if critical
