# Keras framework vulnerable to deserialization of untrusted data

Keras versions 3.11.0 up to 3.11.3 deserialize a TorchModuleWrapper class from a model file, so a malicious .keras file can run arbitrary code when loaded. The code runs even with safe mode enabled.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- pypi:keras affected >= 3.11.0, < 3.11.3 fixed 3.11.3

## How to check

- Run `pip show keras` and look for a version from `3.11.0` up to but not including `3.11.3`
- Search requirements files and lockfiles for `keras` pins in that range

## Fix

- Upgrade the pypi package keras to `3.11.3`
- Only load model files from trusted sources until the upgrade is done

## From the sources

Deserialization of untrusted data can occur in versions of the Keras framework running versions 3.11.0 up to but not including 3.11.3, enabling a maliciously uploaded Keras file containing a TorchModuleWrapper class to run arbitrary code on an end user’s system when loaded despite safe mode being enabled. The vulnerability can be triggered through both local and remote files.
