Vulnerability details

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to insecure input validation when processing serialized data even when "safe_mode" is enabled. A remote attacker can trick the victim into loading a specially crafted Keras v3 model and execute arbitrary code on the system.

This vulnerability exists due to an incomplete fix for #VU106013 (CVE-2025-1550).
