CVE-2026-10198: Assimp glTFImporter glTFImporter.cpp ImportMeshes null pointer dereference

A flaw has been found in Assimp up to 6.0.4. Affected by this vulnerability is the function Assimp::glTFImporter::ImportMeshes of the file glTFImporter.cpp of the component glTFImporter. This manipulation causes null pointer dereference. The attack is restricted to local execution. The exploit has been published and may be used. The project tagged the reported issue as bug.

Security readout for executives and security teams

Plain-English summary

Assimp versions 6.0.0 through 6.0.4 can crash when its glTF importer reaches a null pointer condition in ImportMeshes. The source describes local execution only, so business impact is primarily denial of service in workstations, tools, or pipelines that process glTF assets with Assimp.

Executive priority

Handle as a moderate availability risk, not an emergency remote-code-execution event. Prioritize teams that process external 3D assets or rely on Assimp in automated workflows, because public proof-of-concept material is referenced.

Technical view

CVE-2026-10198 affects Assimp glTFImporter.cpp, function Assimp::glTFImporter::ImportMeshes. VulDB reports a null pointer dereference classified under CWE-476 and CWE-404. CVSS 4.0 is 4.8 with local attack vector, low complexity, low privileges, no user interaction, and low availability impact.

Likely exposure

Exposure is likely where Assimp 6.0.0-6.0.4 is used to import glTF assets. The bundle does not establish remote exposure, but asset-processing services, build pipelines, desktop applications, or security tools using affected Assimp builds should be reviewed.

Exploitation context

The bundle says an exploit has been published and may be used, and includes a GitHub attachment tagged exploit. KEV is false, and the provided sources do not state active exploitation in the wild.

Researcher notes

Evidence is limited to the CVE/VulDB record and upstream issue references in the bundle. No vendor fix version, patch note, or active exploitation confirmation is provided. Validate reachability before escalating, because the CVSS vector is local and availability-only.

Mitigation direction

  • Inventory applications and pipelines using Assimp 6.0.0 through 6.0.4.
  • Check Assimp issue 6609 and vendor guidance for fixed release information.
  • Avoid processing untrusted glTF assets until remediation guidance is confirmed.
  • Run asset-import workflows with least privilege and isolation where practical.
  • Monitor crash telemetry involving Assimp glTF ImportMeshes paths.

Validation and detection

  • Confirm installed Assimp versions across build, desktop, and server environments.
  • Identify whether glTFImporter is compiled in and reachable.
  • Review asset ingestion paths for user-supplied or third-party glTF files.
  • Check logs for recurring Assimp crashes during glTF import.
  • Track the upstream issue for patch or regression-test status.
