CVE-2026-34710
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 - Sampler versions 6.0.0 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 confidenceAn out-of-bounds write vulnerability exists in Substance3D Sampler version 6.0.0 and earlier during file parsing. When a user opens a specially crafted malicious file, the application writes data beyond the boundaries of an allocated buffer, leading to memory corruption and potential 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.
-
Verify if Adobe Substance 3D Sampler is installedCheck the system for the presence of Adobe Substance 3D Sampler application. On Windows, look in Program Files or Program Files (x86) for an Adobe folder containing Substance 3D Sampler. On macOS, check /Applications for Adobe Substance 3D Sampler.app.Affected if The application is found installed on the system
-
Determine the installed version numberOpen Adobe Substance 3D Sampler and navigate to Help > About (or check the application metadata in the installation directory). Alternatively, on Windows right-click the executable, select Properties, and view the Version tab. On macOS, right-click the app, select Get Info, and check the Version field.Affected if The displayed version is 6.0.0 or earlier, or the version cannot be determined (treat as potentially vulnerable)
-
Compare against the affected version rangeReview the version identified in the previous step against the affected range: versions 6.0.0 and earlier are vulnerable. Version 6.0.1 or later contains the fix.Affected if The installed version is 6.0.0 or earlier, indicating the vulnerability is present in the current installation
-
Assess exposure to untrusted file handlingConsider whether the user or others with access to this system open .3ds, .obj, or other 3D model files in Substance 3D Sampler from sources outside the organization or from untrusted email attachments.Affected if The application is actively used to open files from untrusted or external sources, increasing the likelihood of exploitation
The system is affected if Adobe Substance 3D Sampler is installed with version 6.0.0 or earlier and that version is used to open files, as the out-of-bounds write vulnerability can be triggered during file parsing.

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 · scoped6.0.1
Users should refrain from opening untrusted or suspicious files until Adobe releases an official patch. Organizations may consider implementing application whitelisting and file type restrictions as a defense-in-depth measure.
Substance 3D Sampler 6.0.1
- Navigate to the official Adobe website and download Substance 3D Sampler version 6.0.1 or later
- Install the downloaded update using Adobe's standard installation process
- Verify the installed version is 6.0.1 or later by checking the application's version information
