CVE-2026-27219: Substance3D - Painter | Out-of-bounds Read (CWE-125)

Substance3D - Painter versions 11.1.2 and earlier are affected by an Out-of-bounds Read vulnerability that could lead to memory exposure. An attacker could leverage this vulnerability to access sensitive information stored in memory. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Security readout for executives and security teams

Plain-English summary

Adobe Substance 3D Painter 11.1.2 and earlier may reveal sensitive information from memory when a user opens a malicious file. The issue does not alter data or directly disrupt service, but exposed memory could contain confidential material. Successful exploitation requires user interaction.

Executive priority

Treat this as a planned, near-term confidentiality remediation, prioritizing creative teams handling external files. Escalate urgency where Painter processes sensitive projects or files from customers, vendors, or public sources.

Technical view

CVE-2026-27219 is a CWE-125 out-of-bounds read with CVSS 3.1 score 5.5. The supplied vector indicates local attack access, low complexity, no privileges, required user interaction, high confidentiality impact, and no integrity or availability impact.

Likely exposure

Organizations are most exposed where Substance 3D Painter 11.1.2 or earlier processes files received from untrusted or external sources. Systems without Painter, and users who never open attacker-controlled files, are not directly exposed through the described path.

Exploitation context

The victim must open a malicious file in an affected Painter version. The supplied sources do not report active exploitation, and the CVE is not identified as being in CISA's Known Exploited Vulnerabilities catalog.

Researcher notes

The supplied affected-version metadata is ambiguous because it lists endpoints "0" and "11.1.3" while the narrative explicitly states 11.1.2 and earlier. Use the narrative boundary and Adobe advisory for operational decisions. No exploit method, observed attacks, or specific exposed memory contents are documented in the bundle.

Mitigation direction

  • Inventory Substance 3D Painter installations and identify versions 11.1.2 or earlier.
  • Consult Adobe advisory APSB26-25 and apply Adobe's supported remediation guidance.
  • Restrict opening Painter files from untrusted, unsolicited, or externally supplied sources.
  • Use email and file-transfer controls to quarantine suspicious creative-project files.

Validation and detection

  • Confirm installed Painter versions through endpoint inventory and local application records.
  • Verify remediated systems no longer run version 11.1.2 or earlier.
  • Review telemetry for affected users opening unexpected or externally delivered Painter files.
  • Confirm security controls inspect or quarantine untrusted Painter-related file attachments.
