CVE-2026-27022
A query injection vulnerability exists in the @langchain/langgraph-checkpoint-redis package's filter handling.
Does this matter?
Lower severity and a low EPSS score (3.73%). Track it; it rarely justifies an emergency change on its own.
Description
@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.
