Stanza: Remote Code Execution via Unsafe Pickle Deserialization in Model Loaders

Summary Stanza 1.12.0 attempts to safely load PyTorch checkpoint files using torch.load..., weightsonly=True, but automatically falls back to the fully unsafe torch.load..., weightsonly=False when the safe load raises pickle.UnpicklingError. Because the UnpicklingError condition is fully...

CVE-2026-47749

stable-diffusion.cpp is a pure C/C++ library for running diffusion model Stable Diffusion, Flux, Wan, Qwen Image, Z-Image, and more inference. Versions prior to master-584-0a7ae07 are vulnerable to heap buffer overflow in SHORTBINUNICODE parsing for PyTorch checkpoint files. The pickle .ckpt pars...

CVE-2026-47750

The CVE-2026-47750 issue affects stable-diffusion.cpp in its pickle (.ckpt) parser (src/model.cpp). A heap buffer overflow occurs in the GLOBAL opcode handler due to missing validation while locating newline-delimited fields; a crafted .ckpt from an untrusted source can cause the parser to copy w...

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...

CVE-2026-47749

The CVE-2026-47749 entry concerns stable-diffusion.cpp, a C/C++ library for diffusion-model inference. A flaw in the pickle .ckpt parser (src/model.cpp) allows a heap buffer overflow in SHORT_BINUNICODE handling due to sign confusion on the opcode length field. A crafted untrusted .ckpt file coul...

CVE-2026-47749 stable-diffusion.cpp: Heap buffer overflow in SHORT_BINUNICODE 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. Versions prior to master-584-0a7ae07 are vulnerable to heap buffer overflow in SHORTBINUNICODE parsing for PyTorch checkpoint files. The pickle .ckpt pars...

CVE-2026-47748

CVE-2026-47748 affects stable-diffusion.cpp (C/C++ library) prior to master-584-0a7ae07. The root cause is out-of-bounds reads in the PyTorch checkpoint pickle opcode parsing in src/model.cpp, where the parser sometimes advances buffer positions without validating remaining input, allowing reads ...

CVE-2026-31214

The torch-checkpoint-shrink.py script in the ml-engineering project in commit 0099885db36a8f06556efe1faf552518852cb1e0 2025-20-27 contains an insecure deserialization vulnerability CWE-502. The script uses torch.load to process PyTorch checkpoint files .pt without enabling the security-restrictiv...

PT-2026-39635

CosyVoice thru commit 6e01309e01bc93bbeb83bdd996b1182a81aaf11e 2025-30-21 contains an insecure deserialization vulnerability CWE-502 in its average model.py model averaging tool. The script loads PyTorch checkpoint files epoch .pt for model averaging using torch.load without enabling the weights...

Insecure Deserialization

monai is vulnerable to Insecure Deserialization. The vulnerability is due to loading of untrusted checkpoint files like torch.load used without safe guards. This allows an attacker to supply a crafted checkpoint that executes arbitrary code during deserialization...
