CVE-2026-7453 Autodesk CVE debrief

A stack exhaustion vulnerability exists in Autodesk 3ds Max when parsing maliciously crafted WRL (VRML) files. The flaw, classified as CWE-674 (Uncontrolled Recursion), can trigger a denial-of-service condition through local attack vectors. The vulnerability affects 3ds Max versions 2026 and 2027. Autodesk has published security advisory ADSK-SA-2026-0006 addressing this issue. The CVSS 3.1 vector (AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L) indicates a local attack vector requiring user interaction, with low impacts to confidentiality, integrity, and availability.

Who should care

Organizations using Autodesk 3ds Max 2026 or 2027 for 3D modeling and visualization, particularly those processing WRL/VRML files from external or untrusted sources. Security teams should prioritize patching in environments where 3ds Max handles user-supplied content.

Technical summary

The vulnerability stems from improper handling of recursion when parsing WRL (Virtual Reality Modeling Language) files in Autodesk 3ds Max. A malformed WRL file can cause excessive stack consumption, resulting in stack exhaustion and application crash. The attack requires local access and user interaction to open the malicious file. Affected versions include 3ds Max 2026 and 2027. The vulnerability does not appear to be actively exploited in ransomware campaigns based on available data.

Defensive priority

Recommended defensive actions

  • Apply security updates from Autodesk as specified in advisory ADSK-SA-2026-0006
  • Restrict execution of untrusted WRL files in 3ds Max environments
  • Implement application whitelisting to prevent unauthorized 3ds Max execution
  • Monitor for anomalous 3ds Max process crashes that may indicate exploitation attempts
  • Review Autodesk Access for available patches per vendor guidance

Evidence notes

Vulnerability confirmed through official Autodesk security advisory ADSK-SA-2026-0006. CPE configurations specify affected versions as 3ds Max 2026 and 2027. Weakness enumeration identifies CWE-674 (Uncontrolled Recursion) as the root cause.
