Code execution via out-of-bounds memory write
Published Aug 25, 2026 · Updated Aug 27, 2026
Out-of-bounds write in Adobe Substance 3D Painter 12.1.2 and earlier allows attackers to execute code when a user opens a malicious file. Adobe has not identified the affected file parser, input field, or bounds-checking failure that causes the out-of-bounds write. Exploitation requires user interaction, and successful code execution runs in the context of the current user.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
