Listen to this Post
CVE-2026-27214 is a NULL Pointer Dereference vulnerability affecting Adobe Substance 3D Painter versions 11.1.2 and earlier. This flaw occurs when the application attempts to access a memory address that has not been properly initialized (set to NULL) while parsing a specially crafted file. In programming, dereferencing a NULL pointer (trying to use it as if it points to valid data) typically results in an immediate application crash because the operating system prevents access to memory location zero. An attacker can exploit this by creating a malicious project file designed to trigger this unhandled exception upon processing. Successful exploitation requires user interaction, meaning the victim must be tricked into opening the malicious file. The impact is limited to a denial-of-service (application crash), causing disruption and loss of unsaved work, but does not allow for code execution or data exfiltration. The vulnerability is classified as CWE-476 .

What Undercode Say:
Analytics:
- Vulnerability ID: CVE-2026-27214
- CWE: 476 (NULL Pointer Dereference)
- Attack Vector: Local
- User Interaction: Required
- Impact: Application Denial-of-Service (Crash)
Exploit:
A proof-of-concept exploit would involve crafting a file that triggers the flaw.
Example concept: Creating a malformed file header
This is a simplified representation, not the actual exploit.
malformed_header = b"MalformedProject\x00\x00\x00\x00" Triggers NULL deref
with open("exploit_project.spp", "wb") as f:
f.write(malformed_header)
print("[!] Malicious file created. Opening in vulnerable Painter may cause crash.")
Protection from this CVE:
- Patch: Update to Adobe Substance 3D Painter version 11.2.0 or later immediately.
- Mitigation: Avoid opening `.spp` project files from untrusted or unknown sources.
- Verification: Check current version via Help -> About Adobe Substance 3D Painter.
Example bash command to check installed version on Linux (if installed via package manager) dpkg -l | grep substance painter On macOS, check the .app bundle defaults read /Applications/Adobe\ Substance\ 3D\ Painter.app/Contents/Info CFBundleShortVersionString
Impact:
An attacker can cause a direct denial-of-service, leading to application crashes, disruption of creative workflows, and potential loss of unsaved project data for users of vulnerable versions.
