CVE-2026-10710: Autodesk FBX SDK Buffer Overflow Flaw

CVE-2026-10710 Overview

CVE-2026-10710 is a stack-based buffer overflow [CWE-121] in the Autodesk FBX Software Development Kit (SDK). The flaw resides in the fbxsdk::ExtractDrive function used during FBX file parsing. A maliciously crafted FBX file can trigger memory corruption when processed by an application that links the vulnerable SDK. An attacker can leverage the overflow to execute arbitrary code in the context of the current process. Exploitation requires local file delivery and user interaction to open or import the crafted asset.

Critical Impact
Arbitrary code execution in the context of the process parsing an attacker-supplied FBX file, leading to full compromise of confidentiality, integrity, and availability on the affected host.

Affected Products

Autodesk FBX SDK (versions listed in Autodesk Security Advisory ADSK-SA-2026-0010)
Autodesk products and third-party applications that embed the vulnerable FBX SDK
Content pipelines and DCC tools that parse .fbx assets using the affected SDK

Technical Details for CVE-2026-10710

Vulnerability Analysis

The FBX SDK parses the FBX interchange format used across digital content creation and asset pipelines. The vulnerable routine fbxsdk::ExtractDrive writes attacker-controlled data to a fixed-size stack buffer without adequately validating the source length. Parsing a crafted FBX file overflows the buffer, corrupting adjacent stack memory including the saved return address and exception handler pointers.

The classification maps to [CWE-121] Stack-Based Buffer Overflow. Impact is scoped to the process that loads the FBX file, but that process frequently runs with the interactive user's privileges and holds access to project data, source assets, and network shares.

Root Cause

The root cause is missing or incorrect bounds enforcement inside fbxsdk::ExtractDrive when it extracts a drive or path component from a field parsed out of the FBX stream. The function copies data of attacker-controlled length into a stack-allocated buffer sized for expected inputs. Oversized or malformed values overwrite the return address and control the instruction pointer on function return.

Attack Vector

Exploitation is local and requires user interaction. An attacker delivers a crafted .fbx file through email, a shared asset repository, a marketplace download, or a project handoff. When a victim opens or imports the file in an application that uses the affected FBX SDK, fbxsdk::ExtractDrive processes the malicious field and triggers the overflow. Successful exploitation yields code execution in the context of the parsing application.

No verified public exploit code is available. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. See the Autodesk Security Advisory ADSK-SA-2026-0010 for technical details.

Detection Methods for CVE-2026-10710

Indicators of Compromise

Unexpected crashes, access violations, or exception handler failures in applications that parse .fbx files
Child processes spawned by DCC applications (for example cmd.exe, powershell.exe, or rundll32.exe) shortly after an FBX import
.fbx files originating from untrusted email attachments, marketplaces, or unmanaged file shares
New outbound network connections initiated by content creation tools immediately after opening an asset

Detection Strategies

Hunt for process crash telemetry referencing modules exporting fbxsdk::ExtractDrive or the FBX SDK runtime
Alert on FBX-consuming applications launching command interpreters, script hosts, or reflective loaders
Correlate file creation of .fbx files in user download or temp directories with subsequent anomalous process behavior
Apply YARA rules against FBX assets flagged by static parsers as containing oversized path or drive fields

Monitoring Recommendations

Enable Data Execution Prevention (DEP), Control Flow Guard (CFG), and ASLR on all applications embedding the FBX SDK
Forward endpoint process, module load, and crash events to a central data lake for retention and hunting
Track software inventory to identify every application linking a vulnerable version of the Autodesk FBX SDK
Monitor asset repositories and version control for .fbx files introduced by external contributors

How to Mitigate CVE-2026-10710

Immediate Actions Required

Apply the fixed FBX SDK version referenced in Autodesk Security Advisory ADSK-SA-2026-0010 and rebuild downstream applications
Update all Autodesk applications through Autodesk Access to receive vendor-supplied patches
Restrict opening .fbx files sourced from outside the organization until patches are deployed
Inventory third-party tools that redistribute the FBX SDK and confirm each vendor has shipped an updated build

Patch Information

Autodesk has published fixes as described in Security Advisory ADSK-SA-2026-0010. Customers should upgrade to the FBX SDK version listed in the advisory and update any Autodesk product that bundles the SDK. Third-party applications must be recompiled against the patched SDK for the fix to take effect.

Workarounds

Block or quarantine inbound .fbx attachments at the email gateway pending patch deployment
Process untrusted FBX assets only inside isolated virtual machines or sandboxed accounts with no network access
Enforce application allowlisting so DCC tools cannot spawn shells, script interpreters, or unsigned binaries
Remove write access to shared asset repositories for accounts that do not require it, reducing supply-chain injection paths

bash

# Configuration example: quarantine untrusted FBX files on Linux content servers
find /srv/assets/inbox -type f -iname '*.fbx' -newer /var/lib/fbx.lastscan \
  -exec mv {} /srv/assets/quarantine/ \;
touch /var/lib/fbx.lastscan
