Security readout for executives and security teams
Plain-English summary
Adobe Substance 3D Painter 11.1.2 and earlier can expose sensitive information from memory when a user opens a malicious file. The issue does not directly alter data or disrupt systems, but exposed memory could contain confidential content. Because exploitation requires a victim to open a crafted file, risk is concentrated around users handling untrusted project assets.
Executive priority
Prioritize remediation for creative teams routinely exchanging third-party assets. Treat this as a moderate confidentiality risk rather than an emergency outage threat. Prompt patching and tighter handling of untrusted files are appropriate; escalation is warranted where workstations process sensitive client, design, or credential-bearing data.
Technical view
CVE-2026-27216 is a CWE-125 out-of-bounds read with CVSS 3.1 score 5.5. The vector indicates local attack delivery, low complexity, no privileges, required user interaction, and high confidentiality impact without integrity or availability impact. The supplied description identifies Substance 3D Painter 11.1.2 and earlier as affected.
Likely exposure
Workstations running Substance 3D Painter 11.1.2 or earlier are potentially exposed, particularly where users import files from external collaborators, marketplaces, email, or downloads. Systems without Painter, or not opening untrusted files, have lower practical exposure.
Exploitation context
Exploitation requires a user to open a malicious file in the affected application. The provided sources do not report active exploitation, and the CVE is not identified as being in KEV. Absence from KEV does not prove exploitation has never occurred.
Researcher notes
The vulnerability is an out-of-bounds read rather than a write primitive, and the stated impact is memory disclosure. The supplied narrative clearly says 11.1.2 and earlier; the structured affected entry references 11.1.3 without showing its range operator. Confirm exact fixed-version semantics against Adobe APSB26-25 before closing findings.
Mitigation direction
- Inventory Substance 3D Painter installations and identify versions 11.1.2 or earlier.
- Consult Adobe advisory APSB26-25 and deploy the vendor-recommended fixed release.
- Restrict or scrutinize Painter files received from untrusted or unexpected sources.
- Use endpoint controls to limit downloads and opening of suspicious creative assets.
Validation and detection
- Confirm installed Painter versions through software inventory or endpoint management records.
- Verify affected installations were updated according to Adobe advisory APSB26-25.
- Review email, download, and endpoint telemetry for suspicious Painter files.
- Confirm users handling external assets received targeted file-opening guidance.

Out-of-bounds Read
Out-of-bounds Read represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
