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.","state":0,"publishedAt":"2026-10-06T14:45:38.154+00:00","modifiedAt":"2026-10-06T17:39:51.463+00:00","affected":[{"ecosystem":"Vendor product","name":"langchainjs","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"langchain-ai\",\n                    \"product\": \"langchainjs\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.1.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"redis","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"@langchain\",\n                    \"product\": \"redis\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.1.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":2.3,"severity":"LOW"}],"references":["https://github.com/langchain-ai/langchainjs/security/advisories/GHSA-5x6v-p487-7qh2","https://github.com/langchain-ai/langchainjs/pull/10701","https://github.com/langchain-ai/langchainjs/commit/880e3969ea643a2147777a4d5e8bd606a697edf7","https://github.com/langchain-ai/langchainjs/releases/tag/@langchain/redis@1.1.1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-105799","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-105799","identifiers":["CVE-2026-105799"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
