# Assimp: crafted glTF files can read local files from the importing machine

Link for people: https://infrastack.ai/live/CVE-2026-129477 (this .md is for agents)

Assimp, a 3D model loading library, does not restrict buffer paths in glTF and glTF2 files. A crafted model with '..' segments or absolute paths in buffers[].uri can make the importer read files such as /etc/passwd and load their contents into mesh data.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

Assimp through 6.0.6 contains a path traversal vulnerability in the glTF and glTF2 importers that allows attackers to read local files via crafted buffers[].uri values. Attackers can supply glTF models with '..' segments or absolute paths in buffer URIs to load files like /etc/passwd into imported mesh vertex data.
