LangChain Agent Loop Exploit
Definition
A vulnerability where a LangChain ReAct agent gets trapped in a recursive execution cycle (Action -> Observation -> Action) caused by LLM hallucination or indirect prompt injection, resulting in uncontrolled API consumption or cascading system mutations.
Why It Matters
An unconstrained agent loop can execute thousands of database queries, API calls, or LLM token requests per minute. Without an execution boundary, this leads to massive cloud billing spikes, rate-limit bans via third parties (like AWS or Stripe), and complete systemic denial of service.
How Exogram Addresses This
Exogram leverages a deterministic Execution Loop Detector (Rule 4 of the EAAP). It hashes the agent state and tracks execution velocity. If an agent hits a recursive tool threshold without state modification, Exogram instantly blocks the execution token, severing the agent from the infrastructure before billing or damage occurs.
