Code execution via out-of-bounds 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 identifies the memory boundary error but has not published the affected file parser, file format, or the operation that writes beyond its destination buffer. Exploitation requires local user interaction, and successful execution runs with the privileges of the user who opens the crafted file.
