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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-74"],"references":["https://github.com/langchain-ai/langgraphjs/commit/814c76dc3938d0f6f7e17ca3bc11d6a12270b2a1","https://github.com/langchain-ai/langgraphjs/pull/1943","https://github.com/langchain-ai/langgraphjs/releases/tag/@langchain/langgraph-checkpoint-redis@1.0.2","https://github.com/langchain-ai/langgraphjs/security/advisories/GHSA-5mx2-w598-339m"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:24:17.937441719+00:00"},"epss":{"cve":"CVE-2026-27022","score":0.0401,"percentile":0.90556,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-5mx2-w598-339m","url":"https://osv.dev/vulnerability/GHSA-5mx2-w598-339m","summary":"RediSearch Query Injection in @langchain/langgraph-checkpoint-redis","modified":"2026-02-23T23:43:51.425759Z","packages":[{"ecosystem":"npm","name":"@langchain/langgraph-checkpoint-redis","purl":"pkg:npm/%40langchain/langgraph-checkpoint-redis","ranges":["<1.0.2"],"fixed":["1.0.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
