Versions 3.0.0 and below are vulnerable to SQL injection through the checkpoint implementation. Checkpoint allows attackers to manipulate SQL queries through metadata filter keys, affecting applications that accept untrusted metadata filter keys (not just filter values) in checkpoint search operations. The _metadata_predicate() function constructs SQL queries by interpolating filter keys directly into f-strings without validation. This issue is fixed in version 3.0.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-89"],"references":["https://github.com/langchain-ai/langgraph/commit/297242913f8ad2143ee3e2f72e67db0911d48e2a","https://github.com/langchain-ai/langgraph/security/advisories/GHSA-9rwj-6rc7-p77c"],"products":["langchain:langgraph-checkpoint-sqlite"],"source":"nvd","synced_at":"2026-10-19T22:16:40.427100871+00:00"},"epss":{"cve":"CVE-2025-67644","score":0.02306,"percentile":0.83224,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-9rwj-6rc7-p77c","url":"https://osv.dev/vulnerability/GHSA-9rwj-6rc7-p77c","summary":"LangGraph's SQLite is vulnerable to SQL injection via metadata filter key in SQLite checkpointer list method","modified":"2026-07-07T17:56:34.997556097Z","packages":[{"ecosystem":"PyPI","name":"langgraph-checkpoint-sqlite","purl":"pkg:pypi/langgraph-checkpoint-sqlite","ranges":["<3.0.1"],"fixed":["3.0.1"]}]},{"id":"PYSEC-2026-1530","url":"https://osv.dev/vulnerability/PYSEC-2026-1530","summary":"LangGraph's SQLite is vulnerable to SQL injection via metadata filter key in SQLite checkpointer list method","modified":"2026-07-07T17:46:36.795807386Z","packages":[{"ecosystem":"PyPI","name":"langgraph-checkpoint-sqlite","purl":"pkg:pypi/langgraph-checkpoint-sqlite","ranges":["<3.0.1"],"fixed":["3.0.1"]}]}],"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).
