CVE-2025-7262
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 · uneditedIrfanView CADImage Plugin DWG File Parsing Out-Of-Bounds Read Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of IrfanView CADImage Plugin. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of DWG files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-26132.
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 CADImage plugin in IrfanView contains an out-of-bounds read vulnerability when parsing DWG files. The lack of proper validation of user-supplied data during DWG file parsing allows reading past the end of an allocated buffer, which can be leveraged by attackers to achieve remote code execution in the context of the current process.

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.
-
Locate IrfanView installationCheck for IrfanView installation directory, typically in C:\Program Files\IrfanView\ or C:\Program Files (x86)\IrfanView\Affected if IrfanView is not installed (not affected)
-
Check if CADImage plugin is presentExamine the Plugins folder within the IrfanView installation directory for CADImage.dll or similar CADImage plugin filesAffected if CADImage plugin file does not exist (not affected - plugin not installed)
-
Verify CADImage plugin versionRight-click the CADImage plugin DLL file, select Properties, and view the File Version in the Details tab. Alternatively, use a tool like exiftool or check the version through IrfanView's-plugins menuAffected if The displayed version number is lower than 15.0.0.8 (affected)
-
Confirm DWG file handling is possibleAttempt to open a DWG file in IrfanView or verify that CADImage plugin has been used previously to render DWG filesAffected if DWG files have been opened or the plugin is actively used (vulnerability can be triggered)
User is affected if IrfanView with CADImage plugin version below 15.0.0.8 is installed and the plugin has been used or could be used to open untrusted DWG files.

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 · scoped15.0.0.8
Update the IrfanView CADImage Plugin to the latest version from the vendor, or disable the CADImage plugin if not required. Avoid opening untrusted DWG files from unknown sources.
Cadimage 15.0.0.8 or later
- Identify all systems with IrfanView CADImage Plugin installed
- Locate the CADImage plugin DLL file (typically cadimage.dll) in the IrfanView plugin directory
- Download Cadimage version 15.0.0.8 or later from the official vendor (CADImage)
- Replace the existing CADImage plugin file with the updated version
- Verify the plugin loads correctly in IrfanView
- Test with a sample DWG file to confirm functionality
