PYSEC-2026-1528
LangGraph's SQLite store implementation has a SQL Injection Vulnerability
Quick fix
PYSEC-2026-1528 — langgraph-checkpoint-sqlite: upgrade to the fixed version with the command below.
pip install --upgrade 'langgraph-checkpoint-sqlite>=2.0.11'Details
A SQL injection vulnerability exists in the langchain-ai/langgraph repository, specifically in the LangGraph's SQLite store implementation. The affected version is langgraph-checkpoint-sqlite 2.0.10. The vulnerability arises from improper handling of filter operators ($eq, $ne, $gt, $lt, $gte, $lte) where direct string concatenation is used without proper parameterization. This allows attackers to inject arbitrary SQL, leading to unauthorized access to all documents, data exfiltration of sensitive fields such as passwords and API keys, and a complete bypass of application-level security filters.
