CVE-2025-64531
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 3.1.5 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 confidenceA Use After Free vulnerability exists in Substance3D Stager versions 3.1.5 and earlier during file parsing. When processing a maliciously crafted file, memory is deallocated but the program continues to use the freed memory pointer, potentially allowing an attacker to control memory layout and achieve 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 the installed Adobe Substance 3D Stager versionOpen the application and navigate to Help > About (or check the application properties in your installation directory). Alternatively, on Windows check Add/Remove Programs or the application's info.plist on macOS.Affected if The displayed version is 3.1.5 or earlier, or any version lower than 3.1.6
-
Verify the file parsing functionality is accessibleConfirm the application can open or import files (the vulnerability triggers during the parsing of crafted files).Affected if The application has file import or open capabilities enabled and can process external files.
-
Confirm the vulnerability trigger conditionThe Use After Free flaw is triggered specifically when processing a maliciously crafted file. Any user who opens untrusted files in Substance 3D Stager is potentially affected.Affected if Users open files from untrusted sources in the affected application version.
You are affected if Adobe Substance 3D Stager is installed at version 3.1.5 or earlier (any version below 3.1.6) and the application is used to open or parse files.
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 · scoped3.1.6
Update Substance3D Stager to a version newer than 3.1.5 when a patch is released by Adobe. Until then, exercise caution when opening files from untrusted sources.
3.1.6
- Open Substance 3D Stager and navigate to Help > About (or check the application version in its preferences) to confirm the current installed version
- If running version 3.1.5 or earlier, close the application
- Open Adobe Creative Cloud desktop application and navigate to the Apps section
- Find Substance 3D Stager in the list of installed apps and click Update to install version 3.1.6
- Alternatively, download Substance 3D Stager version 3.1.6 directly from Adobe's official website at helpx.adobe.com
- Launch the updated application and verify the version shows 3.1.6
