We audited LangChain/LangGraph for identity security gaps. Here's what we found (and what you need to add yourself)
An audit of LangChain and LangGraph identified identity security gaps related to credential management and agent access control. Key issues include shared credentials across agents without per-agent attribution, lack of a kill switch for instant access revocation, absence of behavioral anomaly detection for unusual agent activity, and no scoped delegated identity for sub-agents. These gaps highlight that LangChain/LangGraph do not provide built-in identity governance and that users must implement their own controls when deploying agents with system access.
AI Analysis
Technical Summary
The audit reviewed LangChain/LangGraph focusing on identity security and credential management. It found that credentials are shared across agents via environment variables or configuration, lacking per-agent credential separation and individual attribution in logs. There is no kill switch to immediately revoke access for a compromised agent without affecting others. Behavioral anomaly detection is missing, so unusual or excessive access patterns are not flagged. In multi-agent setups, sub-agents inherit the orchestrator's credentials without scoped delegation, increasing risk. These are not flaws in LangChain as an orchestration framework but represent gaps users must address for secure production deployments.
Potential Impact
Without per-agent credential separation and kill switch mechanisms, a compromised agent could misuse shared credentials, making it difficult to isolate and revoke access quickly. Lack of behavioral anomaly detection reduces the ability to detect suspicious agent activity. The absence of scoped delegated identities in multi-agent environments increases the risk that sub-agents have excessive privileges. These gaps can lead to unauthorized access, privilege escalation, and difficulty in incident response if agents are compromised.
Mitigation Recommendations
No official patches or fixes exist as these gaps stem from design choices in LangChain/LangGraph, which are orchestration frameworks rather than identity management platforms. Users must implement their own credential management solutions, including per-agent credentials, kill switches to revoke access instantly, behavioral anomaly detection for agent activity, and scoped delegated identities for sub-agents.

Reddit Discussion
Been building in enterprise IAM for a while and recently went through every major agent framework from a credential and identity security perspective. LangChain/LangGraph came up constantly, so I figured this community would find it useful.
The TL;DR: LangGraph is genuinely the most auditable execution model of any framework right now. The graph-based state tracking is great for tracing what ran and when. But that's application-layer observability, not identity governance.
The gaps we found that you have to solve yourself:
Per-agent credentials: LangChain expects you to supply credentials via environment variables or configuration. There's no per-agent credential concept. If 10 agents use the same tool, they all share the same credential. There's no individual attribution in your logs.
Kill switch: There isn't one. If an agent is compromised, you're terminating the process or revoking the credential from the environment. There's no mechanism to instantly cut off one agent's access across all its integrations while leaving others running.
Behavioral anomaly detection: LangSmith gives you token usage and latency traces, which is genuinely useful. It doesn't flag when an agent starts accessing things outside its normal scope or makes an unusual volume of calls to a sensitive system.
Agent-to-agent delegation: In LangGraph multi-agent setups, sub-agents called by an orchestrator inherit the same credential environment. There's no scoped delegated identity. The sub-agent has everything the orchestrator has.
None of this is a criticism of LangChain. It's an orchestration framework, not an IAM platform. But when you move to production with agents that have real system access, these gaps become your problem to solve.
We wrote up the full audit across seven frameworks here if it's useful: https://nullbridge.ai/ai-agent-framework-identity-security-audit
Happy to discuss. I'm curious how people in this community are handling credential management for deployed agents.
