LangChain, a large open source model, has disclosed a severity-level serialization injection vulnerability (CVE-2025-68664), discovered by Yarden Porat, a security researcher at Cyata Security, in which the "lc" key is missing in the serialization/deserialization process. This vulnerability, discovered by Cyata Security security researcher Yarden Porat, is caused by a missing "lc" key in the serialization/deserialization process, which allows an attacker to leak environment variables, instantiate arbitrary objects, or even remotely execute code by means of prompt injection. The vulnerability affects all deployments of LangChain Core before version 0.3.81 and within the range of versions 1.0.0-1.2.5. Officials have released patch versions 1.2.5 and 0.3.81 on December 24th and tightened the default security policy simultaneously.

With the widespread penetration of Large Language Models (LLM) and Generative Artificial Intelligence (GenAI) in enterprise applications, the traditional software security paradigm based on deterministic logic is struggling to cope with new stochastic threats such as model inversion, data poisoning, and cue word injection.Google's Secure AI Framework (SAIF), to be launched in 2023, proposes a systematic defense architecture that aims to combine traditional Cybersecurity best practices with the specificities of Artificial Intelligence (AI) systems. The Secure AI Framework (SAIF), launched by Google in 2023, proposes a systematic defense architecture that aims to combine the best practices of traditional cybersecurity with the specificities of AI systems. In this paper, we will analyze the six core pillars, ecological synergy mechanism and evolution path of SAIF from the perspective of architectural design, providing theoretical and practical references for the construction of enterprise-level AI security system.
