CVE-2023-26393
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 Stager version 2.0.1 (and earlier) is affected by an out-of-bounds read vulnerability when parsing a crafted file, which could result in a read past the end of an allocated memory structure. An attacker could leverage this vulnerability to execute code 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 Stager versions 2.0.1 and earlier contain an out-of-bounds read vulnerability during file parsing. When processing a specially crafted malicious file, the application reads past the end of an allocated memory buffer, potentially allowing arbitrary code execution in the context 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.
-
Locate Adobe Substance 3D Stager installationCheck common installation paths: Windows: C:\Program Files\Adobe\Adobe Substance 3D Stager or C:\Program Files (x86)\Adobe\Adobe Substance 3D Stager. macOS: /Applications/Adobe Substance 3D Stager. Also check Start Menu or Applications folder for the application icon.Affected if Application is installed on the system
-
Find the installed version numberRight-click the Adobe Substance 3D Stager executable or app, select Properties, then look on the Details tab for Product Version. On macOS, right-click the app, select Get Info, and check the Version field. Alternatively, open the app and go to Help > About Adobe Substance 3D Stager.Affected if Version displays as 2.0.1 or lower
-
Compare against affected version rangeCompare the installed version number to the affected range: any version 2.0.1 or earlier is vulnerable. If the version is unknown but the product is installed, treat it as potentially affected.Affected if Installed version is 2.0.1 or any earlier version number
The environment is affected if Adobe Substance 3D Stager version 2.0.1 or earlier is installed, since the out-of-bounds read flaw triggers during parsing of malicious files.
