@langchain/langgraph-checkpoint-redis is the Redis checkpoint and store implementation for LangGraph. A query injection vulnerability exists in the @langchain/langgraph-checkpoint-redis package's filter handling. The RedisSaver and ShallowRedisSaver classes construct RediSearch queries by directly interpolating user-provided filter keys and values without proper escaping. RediSearch has special syntax characters that can modify query behavior, and when user-controlled data contains these characters, the query logic can be manipulated to bypass intended access controls. This vulnerability is fixed in 1.0.2.
AnalysisAI
Query injection in @langchain/langgraph-checkpoint-redis allows authenticated users to manipulate RediSearch filter logic by injecting special syntax characters into user-provided keys and values, potentially bypassing access controls. An attacker with valid credentials could craft malicious filter parameters to alter query behavior and access unintended data. …
