CVE-2026-19568 Overview
CVE-2026-19568 is a memory corruption vulnerability in Autodesk 3ds Max triggered by parsing a maliciously crafted Scalable Vector Graphics (SVG) file. An attacker who convinces a user to open a weaponized SVG in 3ds Max can corrupt process memory and execute arbitrary code in the context of the current user. The flaw is classified under [CWE-120] (Buffer Copy without Checking Size of Input) and requires local user interaction to trigger.
Critical Impact
Successful exploitation grants arbitrary code execution in the context of the 3ds Max process, enabling full compromise of the user's confidentiality, integrity, and availability.
Affected Products
- Autodesk 3ds Max (see Autodesk Security Advisory ADSK-SA-2026-0014 for affected versions)
- Autodesk product installations managed via Autodesk Access

Technical Details for CVE-2026-19568
Vulnerability Analysis
Autodesk 3ds Max supports importing SVG files as vector artwork. When the application parses an SVG file, it copies data from the file into internal memory buffers without correctly validating input length or structure. A crafted SVG element or attribute can overflow one of these buffers and corrupt adjacent memory. This memory corruption can be shaped by an attacker to hijack control flow inside the 3ds Max process.
The vulnerability requires the victim to open the malicious SVG locally, either by launching the file directly or importing it into an existing scene. Exploitation runs code with the privileges of the interactive user. On workstations where artists operate with administrative rights, successful exploitation can lead to full host compromise.
Root Cause
The root cause is a classic buffer-copy weakness in the SVG parser, tracked as [CWE-120]. The parser reads attacker-controlled length or content from the SVG structure and writes it to a fixed-size buffer without a bounds check. This condition enables heap or stack memory corruption depending on the allocation path.
Attack Vector
The attack vector is local and requires user interaction. A typical exploitation scenario involves phishing an artist or engineer with a project archive, marketplace asset, or supplier deliverable that contains the malicious SVG. When the file is opened or imported in 3ds Max, the parser processes the crafted content and the memory corruption primitive is triggered. No verified public proof-of-concept is currently available.
The vulnerability manifests during SVG parsing inside 3ds Max. Refer to Autodesk Security Advisory ADSK-SA-2026-0014 for vendor-supplied technical details.
Detection Methods for CVE-2026-19568
Indicators of Compromise
- Unexpected child processes spawned by 3dsmax.exe, especially command interpreters such as cmd.exe, powershell.exe, or rundll32.exe.
- Crash artifacts or Windows Error Reporting entries referencing 3dsmax.exe immediately after opening or importing an SVG file.
- SVG files delivered via email, chat, or asset marketplaces that contain oversized attribute values, malformed path data, or embedded binary blobs.
- Outbound network connections from 3dsmax.exe to untrusted hosts shortly after a file open event.
Detection Strategies
- Alert on process-creation chains where 3dsmax.exe is the parent of interactive shells, scripting engines, or living-off-the-land binaries.
- Correlate SVG file writes to user directories with subsequent 3ds Max file-open activity to identify potential lure delivery.
- Monitor for module loads and memory-protection changes (VirtualProtect to RWX) within the 3ds Max process, consistent with shellcode execution.
Monitoring Recommendations
- Ingest endpoint telemetry from 3ds Max workstations into a centralized data lake for behavioral analytics and retroactive hunting.
- Track application crash telemetry on artist and CAD workstations to surface exploitation attempts that fail before achieving code execution.
- Baseline normal 3ds Max network activity so that anomalous outbound connections triggered after SVG import are prioritized.
How to Mitigate CVE-2026-19568
Immediate Actions Required
- Apply the fixed version of Autodesk 3ds Max as directed in Autodesk Security Advisory ADSK-SA-2026-0014.
- Use Autodesk Access to inventory installations and deploy the security update across all workstations.
- Instruct users to avoid opening SVG files from untrusted email, chat, or external asset sources until patches are deployed.
- Restrict 3ds Max users to standard accounts to limit the blast radius of code execution in the process context.
Patch Information
Autodesk has issued guidance in ADSK-SA-2026-0014 identifying affected releases and fixed builds of 3ds Max. Consult the advisory for exact version numbers and update packages, and deploy through Autodesk Access or your standard software distribution tooling.
Workarounds
- Block or quarantine inbound SVG attachments at the email gateway pending patch deployment.
- Configure application allowlisting to prevent 3dsmax.exe from spawning shells or scripting hosts.
- Isolate 3ds Max workstations that process third-party assets on network segments with restricted egress.
# Example: hunt for suspicious child processes of 3dsmax.exe in EDR telemetry
# (Adapt to your query language / SIEM schema)
process.parent.name : "3dsmax.exe"
AND process.name : ("cmd.exe" OR "powershell.exe" OR "rundll32.exe" OR "regsvr32.exe" OR "mshta.exe" OR "wscript.exe" OR "cscript.exe")
