CVE-2025-27173
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 - Modeler versions 1.15.0 and earlier are affected by a Heap-based Buffer Overflow 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 Modeler versions 1.15.0 and earlier contain a heap-based buffer overflow vulnerability in their file parsing logic. An attacker can craft a malicious file that, when opened by a victim, triggers the overflow and allows 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.
-
Check if Adobe Substance 3D Modeler is installedOn Windows, check Program Files and Program Files (x86) for the Substance 3D Modeler folder, or use Add/Remove Programs. On macOS, check /Applications for Substance 3D Modeler.app.Affected if The software is present on the system
-
Determine the installed version of Substance 3D ModelerOn Windows, right-click the executable or launcher, select Properties, and check the Version or Details tab for the product version. On macOS, right-click the app, select Get Info, and check the Version field.Affected if The version cannot be determined or the software is installed without version info
-
Compare your installed version to the affected rangeReview the version number found in the previous step against the affected range: any version 1.15.0 or earlier is vulnerable.Affected if The installed version is 1.15.0 or any earlier version number (for example, 1.14.0, 1.10.0, 1.0.0)
-
Identify the file parsing componentThe vulnerability exists in the file parsing logic that handles model files opened within Substance 3D Modeler. No additional configuration check is needed; the vulnerability is present in the core application.Affected if Substance 3D Modeler version 1.15.0 or earlier is running
If Adobe Substance 3D Modeler version 1.15.0 or earlier is installed, the environment is affected by this CVE.
Generated from the published advisory. Verify against your own configuration.
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 · scopedUpdate Substance3D Modeler to a version newer than 1.15.0. Until updated, avoid opening files from untrusted sources.
Substance 3D Modeler 1.16.0 or later
- Navigate to the Adobe Substance 3D Modeler download page or open the Adobe Creative Cloud desktop application
- Check for and install any available updates for Substance 3D Modeler
- Verify the installed version by going to Help > About in the application menu
- Confirm the version number is 1.16.0 or later to ensure the security patch is applied
