CVE-2026-19568: 
Autodesk 3ds Max vulnerability analysis and mitigation

CVE-2026-19568 is a memory corruption vulnerability in Autodesk 3ds Max triggered by parsing a maliciously crafted SVG file, enabling arbitrary code execution in the context of the current process. It affects 3ds Max versions 2026.0.0 through 2026.3.4 (exclusive) and 2027.0.0 through 2027.2.0 (exclusive). The vulnerability was published on August 24, 2026, with a patch made available the same day. It carries a CVSS v3.1 base score of 7.8 (High) (GitHub Advisory, Autodesk Advisory).

The root cause is classified as CWE-120 (Buffer Copy without Checking Size of Input / Classic Buffer Overflow), where the SVG parser in 3ds Max copies input data into a buffer without validating that the input size does not exceed the destination buffer's capacity, resulting in memory corruption. The attack vector is local, requiring no special privileges but necessitating user interaction — specifically, a victim must open a maliciously crafted SVG file within the application. Exploitation could be facilitated through social engineering, phishing, or supply chain attacks delivering a weaponized SVG file to a target user (GitHub Advisory, Autodesk Advisory).

Successful exploitation grants an attacker arbitrary code execution within the security context of the 3ds Max process, resulting in high confidentiality, integrity, and availability impact on the affected system. An attacker could access sensitive project files, intellectual property, or credentials stored on the workstation, modify or destroy data, and potentially crash the application. While the scope is unchanged (limited to the current process), code execution could serve as a foothold for further lateral movement within a network environment (GitHub Advisory).

As of the time of disclosure, there is no known public proof-of-concept exploit and no evidence of active in-the-wild exploitation (Autodesk Advisory). The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog, and NVD's SSVC assessment classifies exploitation as "none" and the vulnerability as not automatable. The EPSS score is approximately 0.127%, placing it in the 3rd percentile for exploitation likelihood within 30 days (GitHub Advisory).

1. Craft malicious SVG file: Create a specially crafted SVG file containing oversized or malformed data elements designed to overflow a buffer in 3ds Max's SVG parsing component, triggering memory corruption.
2. Deliver the file: Distribute the malicious SVG to a target 3ds Max user via phishing email, shared network drive, compromised asset repository, or social engineering (e.g., posing as a legitimate design asset).
3. Induce user interaction: Convince the victim to open the malicious SVG file within Autodesk 3ds Max (versions 2026.0.0–2026.3.3 or 2027.0.0–2027.1.x).
4. Trigger memory corruption: Upon parsing the SVG, the vulnerable buffer copy routine writes beyond the allocated buffer boundary, corrupting adjacent memory structures.
5. Achieve code execution: By controlling the overwritten memory (e.g., return address or function pointer), the attacker redirects execution flow to attacker-controlled shellcode or a ROP chain, executing arbitrary code in the context of the 3ds Max process (GitHub Advisory, Autodesk Advisory).

• File System: Unexpected SVG files in project directories, download folders, or shared drives; new or modified executable files created in the 3ds Max installation directory or user profile directories following application use.
• Process: Unusual child processes spawned by the 3ds Max process (e.g., cmd.exe, powershell.exe, curl, wget); 3ds Max process crashing or generating crash dump files (*.dmp) unexpectedly.
• Logs: Application crash logs or Windows Event Log entries (Event ID 1000/1001) referencing 3ds Max (3dsmax.exe) with faulting module related to SVG parsing; Dr. Watson or Windows Error Reporting logs indicating memory access violations in 3ds Max.
• Network: Unexpected outbound network connections originating from the 3ds Max process to external IP addresses, particularly shortly after opening an SVG file.

Autodesk has released patched versions: 3ds Max 2026.3.4 and 3ds Max 2027.2, which address this vulnerability (Autodesk Advisory). Users should update to these versions immediately via the Autodesk Access application. As interim workarounds, restrict access to 3ds Max installations, avoid opening SVG files from untrusted or unverified sources, and implement file type filtering or sandboxing to prevent loading potentially malicious SVG files into the application (GitHub Advisory).
