CVE-2026-47747

The CVE affects stable-diffusion.cpp, a pure C/C++ library for running diffusion model inference. The vulnerability lies in the pickle .ckpt parser in src/model.cpp within versions prior to master-584-0a7ae07, where a heap-based overflow could occur in the BINUNICODE opcode handler due to sign co...

CVE-2026-47750 stable-diffusion.cpp: Heap buffer overflow in GLOBAL opcode parsing for PyTorch checkpoint files

stable-diffusion.cpp is a pure C/C++ library for running diffusion model Stable Diffusion, Flux, Wan, Qwen Image, Z-Image, and more inference. In versions prior to master-584-0a7ae07, the pickle .ckpt parser in src/model.cpp contained a heap buffer overflow vulnerability in the GLOBAL opcode...
