CVE-2026-12484: Keras Unsafe Deserialization in TorchModuleWrapper
CVE-2026-12484
CVE-2026-12484
Summary
A security flaw in Keras version 3.15.0 allows attackers to execute arbitrary code by manipulating PyTorch pickle data. This can happen when Keras processes untrusted configuration files. To fix this, update to a newer version of Keras that includes the necessary security patches.
What to do

Original description
A vulnerability in keras-team/keras version 3.15.0 allows unsafe deserialization of attacker-controlled PyTorch pickle data through the public `keras.layers.TorchModuleWrapper.from_config` method. This method invokes `torch.load(..., weights_only=False)` without requiring an explicit unsafe opt-in, such as a `safe_mode=False` parameter. When called outside a `SafeModeScope(True)` context, the absence of an ambient safe mode state permits unsafe deserialization by default. This issue can lead to arbitrary code execution if untrusted Keras layer configurations are processed using this method. The vulnerability arises because the method does not enforce safe deserialization practices unless explicitly guarded by Keras safe mode.
