# GPAC: crafted XMT scene file crashes MP4Box and scene loaders

Link for people: https://infrastack.ai/live/CVE-2025-71467 (this .md is for agents)

GPAC before 26.02.0 has a NULL pointer dereference in gf_node_get_field_by_name() that a crafted XMT scene can trigger. An attacker who gets a team to load the file crashes MP4Box or the GPAC scene loader, causing denial of service.

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

## How to check

- Run `MP4Box -version` or `gpac -version` and compare against `26.02.0`
- Check whether your pipeline or service loads untrusted XMT scene files

## Fix

- GPAC: upgrade to `26.02.0` or later

- [fix] Patch: github.com https://github.com/gpac/gpac/commit/62714f27c64a3d1eb7e880f9eed2d38673cb43ce

## From the sources

GPAC before 26.02.0 contains a NULL pointer dereference vulnerability in gf_node_get_field_by_name() in src/scenegraph/base_scenegraph.c that lets attackers crash applications. Attackers can supply a crafted XMT scene referencing a never-created node to crash MP4Box or GPAC scene loader applications, causing denial of service.
