CVE-2025-49655 · Severity: critical · CVSS 9.8 · Published 2025-10-17

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.

Technologies: keras (PyPI). Vendors: PyPI.
