CVE-2025-43568
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 · uneditedSubstance3D - Stager versions 3.1.1 and earlier are affected by a Use After Free 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 confidenceSubstance3D Stager versions 3.1.1 and earlier contain a Use After Free vulnerability that can be triggered when parsing a specially crafted malicious file. Upon successful exploitation, an attacker can achieve arbitrary code execution with the privileges of the current user. The vulnerability requires user interaction (opening a malicious file), which reduces the attack surface but still poses significant risk.

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.
-
Identify installed Substance3D Stager versionLocate Adobe Substance 3D Stager in your installed applications and retrieve its version number. On Windows, check Add/Remove Programs or the application executable properties. On macOS, right-click the application in Applications and select Get Info, or use 'mdls' command.Affected if The installed version is 3.1.1 or earlier (versions below 3.1.2 are affected)
-
Compare version against vulnerable rangeCompare the version number you found to the affected range: any version below 3.1.2 is vulnerable. The fixed version is 3.1.2.Affected if The version is lower than 3.1.2
-
Assess file parsing exposureDetermine if the system is used to open, import, or parse .stg project files or other Substance 3D Stager file formats. This is the attack vector that triggers the Use After Free vulnerability.Affected if Users open .stg or related project files from potentially untrusted sources on this system
A system is affected if Adobe Substance 3D Stager version 3.1.1 or earlier is installed and users open malicious .stg project files with it.

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 · scoped3.1.2
Update Substance3D Stager to a version newer than 3.1.1 when Adobe releases a patch. Until then, exercise caution and avoid opening .stg or related project files from untrusted or unknown sources.
Substance 3D Stager 3.1.2
- Navigate to the official Adobe Substance 3D Stager download page on helpx.adobe.com
- Download Substance 3D Stager version 3.1.2 or later
- Close any running instances of Substance 3D Stager
- Run the installer and follow the prompts to upgrade the software
- Restart the application after installation completes
- Verify the installed version by checking Help > About in the application
