CVE-2026-12484Public exploit

Code execution via fail-open PyTorch pickle loading

Published Jul 19, 2026 · Updated Jul 19, 2026

Unsafe deserialization in Keras 3.15.0 allows local users to execute code through a crafted TorchModuleWrapper configuration. TorchModuleWrapper.from_config passes attacker-controlled pickle bytes to torch.load with weights_only=False when no safe-mode state is set. Exploitation requires an application or user to process the untrusted configuration outside SafeModeScope(True), after which pickle reconstruction executes with the Keras process's privileges.
