  • •LangGraph has 46.5 million downloads, making its vulnerabilities highly impactful.
  • •An SQL injection combined with a deserialization flaw enables remote code execution.
  • •Three CVEs have been assigned, and organizations should prepare for imminent patches.

Check Point Research identified critical vulnerabilities in LangGraph, an AI framework with 46.5 million downloads last month. The flaws allow attackers to execute remote code and gain control over affected servers. The vulnerabilities stem from an SQL injection in the get_state_history() function combined with a deserialization issue. These issues can lead to unauthorized access to sensitive data, including API keys and conversation histories. LangGraph is widely used for automating tasks in corporate environments, making the impact potentially severe. The vulnerabilities have been assigned three CVEs, and the LangChain team is working on fixes. Organizations using LangGraph are advised to monitor their systems closely and apply patches once available.
