    CVE-2026-24747 (GCVE-0-2026-24747)

    Vulnerability from nvd – Published: 2026-01-27 21:13 – Updated: 2026-06-30 12:06

    Title
    PyTorch Vulnerable to Remote Code Execution via Untrusted Checkpoint Files
    Summary
    PyTorch is a Python package that provides tensor computation. Prior to version 2.10.0, a vulnerability in PyTorch's `weights_only` unpickler allows an attacker to craft a malicious checkpoint file (`.pth`) that, when loaded with `torch.load(..., weights_only=True)`, can corrupt memory and potentially lead to arbitrary code execution. Version 2.10.0 fixes the issue.

    Title
    PyTorch: `torch.load` with `weights_only=True` leads to remote code execution
    Summary
    PyTorch is a Python package that provides tensor computation with strong GPU acceleration and deep neural networks built on a tape-based autograd system. In version 2.5.1 and prior, a Remote Command Execution (RCE) vulnerability exists in PyTorch when loading a model using torch.load with weights_only=True. This issue has been patched in version 2.6.0.

    CVE-2026-24747 (GCVE-0-2026-24747)

    Vulnerability from cvelistv5 – Published: 2026-01-27 21:13 – Updated: 2026-06-30 12:06
    VLAI
    Title
    PyTorch Vulnerable to Remote Code Execution via Untrusted Checkpoint Files
    Summary
    PyTorch is a Python package that provides tensor computation. Prior to version 2.10.0, a vulnerability in PyTorch's `weights_only` unpickler allows an attacker to craft a malicious checkpoint file (`.pth`) that, when loaded with `torch.load(..., weights_only=True)`, can corrupt memory and potentially lead to arbitrary code execution. Version 2.10.0 fixes the issue.

    Title
    PyTorch: `torch.load` with `weights_only=True` leads to remote code execution
    Summary
    PyTorch is a Python package that provides tensor computation with strong GPU acceleration and deep neural networks built on a tape-based autograd system. In version 2.5.1 and prior, a Remote Command Execution (RCE) vulnerability exists in PyTorch when loading a model using torch.load with weights_only=True. This issue has been patched in version 2.6.0.

    AVID-2023-V015

    Vulnerability from avid – Published: 2023-03-31 – Updated: 2023-03-31 ATLAS Case Study
    Summary
    Linux packages for PyTorch's pre-release version, called Pytorch-nightly, were compromised from December 25 to 30, 2022 by a malicious binary uploaded to the Python Package Index (PyPI) code repository. The malicious binary had the same name as a PyTorch dependency and the PyPI package manager (pip) installed this malicious package instead of the legitimate one. This supply chain attack, also known as "dependency confusion," exposed sensitive information of Linux machines with the affected pip-installed versions of PyTorch-nightly. On December 30, 2022, PyTorch announced the incident and initial steps towards mitigation, including the rename and removal of `torchtriton` dependencies.
