CVE-2025-67644Public exploit

Arbitrary SQL execution via unvalidated metadata keys

Published Dec 10, 2025 · Updated Dec 11, 2025

SQL injection in LangGraph SQLite Checkpoint before 3.0.1 allows attackers to execute arbitrary SQL through metadata filter keys. The _metadata_predicate() function interpolates each key into a json_extract expression without validation while parameterizing only its value. Reachability requires an application that uses SqliteSaver checkpoint search and accepts untrusted filter keys; injected predicates can bypass filtering and expose checkpoint data.
