LangGraph SQLite Checkpoint is an implementation of LangGraph CheckpointSaver that uses SQLite DB (both sync and async, via aiosqlite). Prior to 2.0.11, LangGraph's SQLite store implementation contains SQL injection vulnerabilities using direct string concatenation without proper parameterization, allowing attackers to inject arbitrary SQL and bypass access controls. This vulnerability is fixed in 2.0.11.

Affected: PyPI: langgraph-checkpoint-sqlite

### Summary LangGraph's SQLite store implementation contains SQL injection vulnerabilities using direct string concatenation without proper parameterization, allowing attackers to inject arbitrary SQL and bypass access controls.

### Details [`/langgraph/libs/checkpoint-sqlite/langgraph/store/sqlite/base.py`](https://github.com/langchain-ai/langgraph/blob/ee5d052a07aadd76dae123a27009ea0a3694fa0a/libs/checkpoint-sqlite/langgraph/store/sqlite/base.py#L407)

The key portion of the JSON path is concatenated directly into the SQL string without sanitation. There's a few different occurrences within the file.

```python filter_conditions.append( "json_extract(value, '$." + key # <-- Directly concatenated, no escaping! + "') = '" + value.replace("'", "''") # <-- Only value is escaped + "'" ) ```

### Who is affected

This issue affects **only developers or projects that directly use the `checkpoint-sqlite` store**.

An application is vulnerable only if it: 1. Instantiates the `SqliteStore` from the `checkpoint-sqlite` package, **and** 2. Builds the `filter` argument using keys derived from **untrusted or user-supplied input** (such as query parameters, request bodies, or other external data).

If filter keys are static or validated/allowlisted before being passed to the store, the risk does not apply.

Note: users of LangSmith deployments (previously known as LangGraph Platform) are not affected as those deployments rely on a different checkpoin…
