CVE-2026-116103 - Vulnerability Details

- Sony Neural Network Libraries Encode Param encode_decode_param.py load_param_in_txt code injection

Description

A vulnerability was identified in Sony Neural Network Libraries up to 1.39.0. This affects the function load_param_in_txt of the file python/src/nnabla/utils/cli/encode_decode_param.py of the component Encode Param Command Handler. Such manipulation leads to code injection. It is possible to launch the attack remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way. This vulnerability only affects products that are no longer supported by the maintainer.
