Summary
GPAC through 26.07.0 Use-After-Free in gf_sg_proto_del During Scene Teardown
Details

GPAC through 26.07.0 contains a use-after-free vulnerability in gf_sg_proto_del() in src/scenegraph/vrml_proto.c because gf_sg_reset() frees unregistered prototypes still referenced by scene commands. Attackers can supply a crafted XMT/BT scene declaring prototypes via commands, processed by MP4Box -chap, to trigger freed memory access and crash the process.
