langchain-ai/langchain — Vulnerabilities & Security Advisories 12

This page documents common weaknesses and security vulnerabilities associated with the open-source LangChain project hosted by langchain-ai. It aggregates issues that arise from the framework’s extensive integration capabilities, complex agent orchestration logic, and reliance on third-party tools, which can introduce risks such as injection attacks, data leakage, and unauthorized execution flows. The collection covers security advisories, reported flaws, and community-disclosed issues identified between 2023 and 2024, reflecting the rapid evolution of the library during its initial growth phase. Visitors can use this resource to track vendor advisories from the LangChain maintainers, understand the specific characteristics of weakness classes affecting large language model applications, and look up a product’s vulnerability history to assess exposure. By reviewing these aggregated entries, developers and security professionals can gain insight into how chain construction, tool usage, and memory management might lead to exploitable conditions in real-world deployments. This overview serves as a neutral reference for understanding the attack surface inherent in the framework without implying severity or recommending specific mitigation strategies beyond general best practices. The data is compiled from public sources including GitHub issues, pull requests, and security research reports to provide a comprehensive view of the known defects in this popular AI development toolkit.
