CVE-2026-105799

LangChain: RediSearch Filter Injection via Unescaped Tag/Text Values

Published Oct 6, 2026 CVSS 4.0 · 2.3 Low EPSS < 1% KEV · Not listed
Description
LangChain is a framework for building LLM-powered applications. Prior to 1.1.1, @langchain/redis does not escape attacker-controlled values in structured RediSearch TAG filters and structured RediSearch TEXT filters, allowing injected RediSearch syntax to alter or broaden the generated search query. When an application uses an attacker-influenceable filter as a tenant or document-access boundary, the modified query can expose indexed documents outside the attacker's intended scope. This issue is fixed in version 1.1.1.
