GPAC through 26.07.0 contains a type confusion vulnerability in gf_sg_command_apply() in src/scenegraph/commands.c that fails to verify BIFS field-replace command types match target node fields. Attackers can supply a crafted XMT file opened with MP4Box, such as via chapter import, causing gf_sg_vrml_field_clone() to memcpy from invalid pointers and crash.
