Vulnerability from fkie_nvd - Published: 2026-02-20 22:16 - Updated: 2026-04-15 00:35
Severity ?
6.5 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Summary
@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.

RediSearch tiene caracteres de sintaxis especiales que pueden modificar el comportamiento de las consultas, y cuando los datos controlados por el usuario contienen estos caracteres, la l\u00f3gica de la consulta puede ser manipulada para eludir los controles de acceso previstos. Esta vulnerabilidad est\u00e1 corregida en la versi\u00f3n 1.0.2."
