CVE-2026-7450
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA maliciously crafted PAR file, when parsed through Autodesk 3ds Max, can force a NULL Pointer Dereference vulnerability. Successful exploitation may cause the application to crash, leading to a denial-of-service condition.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA NULL Pointer Dereference vulnerability exists in Autodesk 3ds Max when parsing maliciously crafted PAR (scene) files. During file parsing, the application attempts to dereference a NULL pointer without proper validation, causing an access violation and application crash.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed 3ds Max versionOpen 3ds Max and navigate to Help > About Autodesk 3ds Max, or right-click the 3ds Max executable and select Properties > Details to view the Product VersionAffected if The displayed version is 2026 or 2027
-
Confirm PAR file support is presentVerify that the 3ds Max installation includes PAR (parameter) file import/export capabilities by checking if the File > Import menu lists PAR files or by searching for PAR-related plugins in the plugins folderAffected if PAR file parsing functionality exists in the installation
-
Identify PAR file handling pathwayAttempt to locate the PAR file importer module or check the application log for PAR-related loading messages when opening a sample PAR fileAffected if The application loads and processes PAR files through its parsing pipeline
-
Verify vulnerable code path is reachableCheck if the PAR parser module (typically named something like parimporter.dli or parse.dlu) is loaded by the application - this can be confirmed by monitoring loaded modules or checking installation directories for PAR-related DLLsAffected if PAR parsing DLLs are present and loadable by the application
The environment is affected if Autodesk 3ds Max version 2026 or 2027 is installed and the application can parse PAR (parameter) files, as the NULL pointer dereference triggers during PAR file parsing operations.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor-supplied patch when available; in the interim, implement file type restrictions to block untrusted PAR files and educate users against opening files from untrusted sources.
