CVE-2026-24747: PyTorch Vulnerable to Remote Code Execution via Untrusted Checkpoint Files

Severity: high (CVSS 8.8 v3.1)
Exploited in the wild: not listed in CISA KEV
EPSS: 0.8% probability of exploitation in the next 30 days
Public exploit or detection template: yes
Published: 2026-01-27 · updated 2026-07-15
Weakness: CWE-94

Description

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.

Affected products

PyTorch: before 2.10.0 — fixed in 2.10.0

How to fix

Upgrade to a fixed version: PyTorch 2.10.0. Check the vendor advisory for mitigations.
