CVE-2026-9260
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 · uneditedUse of hard-coded cryptographic keys in Canon EOS Network Setting Tool Version 1.5.0 or earlier
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 · high confidenceThe Canon EOS Network Setting Tool version 1.5.0 and earlier contains hard-coded cryptographic keys embedded in the software binary or source code. This critical vulnerability allows attackers to decrypt communications, bypass authentication, or access sensitive network configurations since the same key is used across all installations.
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 checksWork through these to decide whether this CVE applies to you.
-
Check installed version of Canon EOS Network Setting ToolOpen the application or check the file properties of the installed executable. On Windows, right-click the executable and select Properties > Details to view the File Version. On macOS, right-click and select Get Info. The version is typically listed as '1.5.0', '1.4.x', or earlier.Affected if The installed version is 1.5.0 or any version earlier than 1.5.1 (e.g., 1.4.0, 1.3.0)
-
Inspect the application binary for embedded cryptographic materialUse a tool like 'strings' on Linux/macOS (run: strings CanonEOSNetworkSettingTool | grep -i 'key\|crypto\|aes\|DES\|3DES') or BinText on Windows to search the executable for readable strings that resemble encryption keys, IVs, or cryptographic constants. Look for hard-coded values that appear to be keys rather than algorithm identifiers.Affected if The binary contains visible strings that match patterns of cryptographic keys, IVs, or appear to be reusable secret values embedded in the code
-
Check if the tool is currently in use or scheduled tasks existOpen Task Manager on Windows or use 'ps aux' on Linux to check if CanonEOSNetworkSettingTool.exe or related processes are running. Also check Task Scheduler for any automated network configuration tasks using this tool.Affected if The tool is actively running or configured to run automatically, exposing the hard-coded keys during network operations
-
Verify network exposure of the tool's communicationsUse network monitoring tools (such as Wireshark or netstat) to observe if the Canon EOS Network Setting Tool is sending or receiving network traffic on ports used for camera network configuration (typically HTTP ports 80/443 or vendor-specific ports).Affected if The tool is communicating over the network and its traffic could potentially be decrypted using the embedded key
A user is affected if the installed Canon EOS Network Setting Tool version is 1.5.0 or earlier, and the tool is being used on the network, as the hard-coded cryptographic keys in the binary could allow attackers to decrypt communications or bypass authentication.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.5.1
Organizations using this tool should check for and apply any vendor updates from Canon that remove hard-coded keys. If no patch is available, avoid using the tool on untrusted networks and consider alternative methods for network configuration until a fix is released.
1.5.1
- Navigate to the official Canon support website (canon.jp, psirt.canon, canon-europe.com, or usa.canon.com)
- Locate the EOS Network Setting Tool download page
- Download version 1.5.1 or later of the EOS Network Setting Tool
- Uninstall any existing version of EOS Network Setting Tool
- Install the newly downloaded version 1.5.1
- Verify the installed version is 1.5.1 or later by checking the application version information
