Substance3D - 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.
AnalysisAI
Arbitrary code execution in Adobe Substance3D Sampler 6.0.0 and earlier occurs when a user opens a maliciously crafted asset file that triggers an out-of-bounds write in the application's parsing logic. Exploitation runs in the context of the logged-in user and requires user interaction to open the file; no public exploit identified at time of analysis and the issue is not listed in CISA KEV.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Victim must locally open a malicious file (project, material, or scan package) in Adobe Substance3D Sampler 6.0.0 or earlier - this is the user-interaction requirement encoded as UI:R in the CVSS vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 7.8 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) reflects a local attack vector that still requires the victim to open a file, which is the dominant limiter on real-world risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker distributes a weaponized Substance3D material or scene file via a compromised asset marketplace, freelance-artist handoff, or spear-phishing email targeting a VFX or game studio. When an artist opens the file in Sampler 6.0.0 or earlier, the malformed structure triggers the out-of-bounds write and the attacker gains code execution as that user - typically enough to deploy a loader, harvest credentials, and pivot into the studio's render farm or source repositories. |
| Remediation | Patch available per vendor advisory APSB26-60 - upgrade Substance3D Sampler to the fixed version listed at https://helpx.adobe.com/security/products/substance3d-sampler/apsb26-60.html using the Creative Cloud desktop app or enterprise admin console; the exact fixed version number was not provided in the input data, so verify against the advisory before rollout. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Issue urgent communication to all Substance3D Sampler users warning against opening asset files from untrusted sources; disable or restrict the application where non-essential. …
