CVE-2025-8709Public exploit

Protected-data disclosure via concatenated SQLite filter keys

Published Oct 26, 2025 · Updated Oct 26, 2025

SQL injection in LangGraph's SQLite store 2.0.10 and earlier allows local users to read protected documents via crafted filter keys. The SqliteStore filter builders interpolate each filter key into json_extract WHERE expressions without validating or binding it as data. A low-privileged caller who can submit a filter to an application using this store can alter query structure, bypass application filters, and retrieve private records; LangSmith deployments use a different checkpointer and are unaffected.
