Analysis

AI-generated

Technical impact

Substance3D Painter versions earlier than 12.0.2 contain an out‑of‑bounds write (CWE‑787) that can be used to overwrite memory and execute arbitrary code when a user opens a crafted file. The flaw does not allow remote exploitation; the attacker must supply a malicious file and the victim must interact with it, typically by double‑clicking or opening the file within the application.

Affected Systems

Adobe Substance3D Painter 12.0.2 and earlier are affected.

Risk and Exploitability

The CVSS score of 7.8 indicates a high severity vulnerability, but the EPSS score is not available and the flaw is not listed in the CISA KEV catalog. Exploitation requires user interaction through a malicious file, meaning the attack is local and depends on the user opening the infected document. While the risk is significant for users who regularly open external files, the lack of a remote exploit vector reduces the overall threat compared to remote code execution scenarios.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade to the latest Adobe Substance3D Painter release that resolves the out‑of‑bounds write flaw
  • If an upgrade cannot be performed immediately, run Painter in a sandboxed or isolated environment to contain any potential compromise
  • Ensure that files are scanned with up‑to‑date antivirus or other security software before opening them in the application
