CVE-2023-48639
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 · uneditedAdobe Substance 3D Designer versions 13.0.0 (and earlier) and 13.1.0 (and earlier) are affected by an out-of-bounds write vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
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 confidenceAdobe Substance 3D Designer contains an out-of-bounds write vulnerability in its file parsing logic. When processing maliciously crafted files (likely graph, substance, or 3D asset files), the application writes data beyond allocated memory boundaries, potentially allowing an attacker to achieve arbitrary code execution with the privileges of the current user.

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.
-
Confirm Adobe Substance 3D Designer is installedCheck for the application in the standard installation directory (Windows: C:\Program Files\Adobe\Adobe Substance 3D Designer or Mac: /Applications/Adobe Substance 3D Designer) or look for it in the system application listAffected if The application is found on the system
-
Identify the installed version numberRight-click the application executable (e.g., Adobe Substance 3D Designer.exe) and select Properties, then view the Details tab for the Product Version. On Mac, Control-click the app in Applications and select Get Info to view the Version fieldAffected if A version number is displayed in the Properties or Info window
-
Compare your version to the affected rangeCompare the installed version you found against the affected range: version 13.0.0 and any earlier versionsAffected if The installed version is 13.0.0 or lower (for example, 13.0.0, 12.x, 11.x, etc.)
-
Verify the file parsing component is presentConfirm the application includes its file import functionality by launching the application and checking if you can access the File > Open or File > Import menu optionsAffected if The file open/import functionality is available and the vulnerable version is installed
You are affected if Adobe Substance 3D Designer version 13.0.0 or earlier is installed on your system, as the vulnerability resides in the file parsing logic of these versions.
