CVE-2025-67644: PYSEC-2026-1530 - LangGraph's SQLite is vulnerable to SQL injection via metadata filter key in SQLite checkpointer list method

CVE-2025-67644 · Severity: high · CVSS 7.3 · Published 2025-12-11

LangGraph SQLite Checkpoint is an implementation of LangGraph CheckpointSaver that uses SQLite DB (both sync and async, via aiosqlite). Versions 3.0.0 and below are vulnerable to SQL injection through the checkpoint implementation. Checkpoint allows attackers to manipulate SQL queries through metadata filter keys, affecting applications that accept untrusted metadata filter keys (not just filter values) in checkpoint search operations. The _metadata_predicate() function constructs SQL queries by interpolating filter keys directly into f-strings without validation. This issue is fixed in version 3.0.1.

Technologies: langgraph-checkpoint-sqlite (PyPI). Vendors: LangChain, PyPI.
