CVE-2026-16782 Overview
CVE-2026-16782 is an out-of-bounds read vulnerability in Autodesk 3ds Max that occurs when the application parses a maliciously crafted Scalable Vector Graphics (SVG) file. An attacker who convinces a user to open a specially crafted SVG can trigger the flaw during file parsing. Successful exploitation can cause a process crash, disclose sensitive data from adjacent memory, or, under specific conditions, allow arbitrary code execution in the context of the current process. The weakness is classified as [CWE-125] Out-of-bounds Read.
Critical Impact
A crafted SVG file processed by Autodesk 3ds Max can leak sensitive memory contents, crash the application, or execute code in the current user context.
Affected Products
- Autodesk 3ds Max (versions listed in the vendor advisory)
- Autodesk Access is the recommended update channel for affected releases
- Refer to the Autodesk Security Advisory ADKS-SA-2026-0014 for the full version list

Technical Details for CVE-2026-16782
Vulnerability Analysis
The vulnerability resides in the SVG parsing logic used by Autodesk 3ds Max. When the parser processes attacker-controlled structures inside an SVG document, it reads memory beyond the bounds of an allocated buffer. Because SVG is an XML-based vector format with many optional elements, attributes, and numeric fields, malformed length indicators or missing terminators can drive the parser past the end of a source buffer.
The out-of-bounds read exposes adjacent process memory to the application's parsing routines. That memory can include heap metadata, pointers, or previously processed document contents. In some execution paths, the leaked data influences subsequent control flow, which is why the advisory notes possible arbitrary code execution in addition to information disclosure and denial of service.
Exploitation requires the victim to open or import the crafted SVG in 3ds Max. No authentication is required, and no elevated privileges are needed on the target.
Root Cause
The root cause is missing or insufficient bounds validation while iterating over SVG element data. The parser trusts size or index values derived from the input file rather than validating them against the actual buffer length before dereferencing, resulting in a read past the allocated region.
Attack Vector
An attacker delivers a malicious .svg file through email, a shared project directory, a compromised asset repository, or a web download. When the user imports or previews the file in Autodesk 3ds Max, the parser triggers the out-of-bounds read. See the Autodesk Security Advisory ADKS-SA-2026-0014 for authoritative technical details.

Detection Methods for CVE-2026-16782
Indicators of Compromise
- Unexpected crashes of 3dsmax.exe shortly after opening or importing an SVG file
- Windows Error Reporting (WER) entries referencing access violations in 3ds Max modules during SVG parsing
- SVG files arriving from untrusted senders that reference external content or contain malformed numeric attributes
Detection Strategies
- Monitor endpoint telemetry for 3dsmax.exe process crashes correlated with recent SVG file opens
- Inspect email and file-sharing gateways for SVG attachments delivered to workstations running Autodesk 3ds Max
- Baseline normal 3ds Max child-process and memory behavior, and alert on deviations that follow SVG import events
Monitoring Recommendations
- Enable application crash logging and forward it to a centralized SIEM for correlation
- Track file-open and import events for .svg files on hosts with Autodesk 3ds Max installed
- Review Autodesk Access update logs to confirm that patched builds are deployed across the fleet
How to Mitigate CVE-2026-16782
Immediate Actions Required
- Apply the fixed Autodesk 3ds Max version identified in ADKS-SA-2026-0014 using Autodesk Access
- Instruct users to avoid opening SVG files received from untrusted or unverified sources
- Inventory all workstations running Autodesk 3ds Max and confirm patch status
Patch Information
Autodesk has published fixed builds through security advisory ADKS-SA-2026-0014. Updates should be deployed via Autodesk Access or the corresponding installer channel. Consult the advisory for the specific product versions and build numbers that remediate CVE-2026-16782.
Workarounds
- Do not import or preview SVG files from untrusted sources until the patch is applied
- Restrict SVG file delivery through email and collaboration platforms using content filtering rules
- Store project assets in access-controlled repositories to reduce exposure to attacker-supplied SVG content
