The affected version is 0.3.63. The vulnerability arises from the use of etree.iterparse() without disabling external entity references, which can lead to sensitive information disclosure. An attacker could exploit this by crafting a malicious XML payload that references local files, potentially exposing sensitive data such as /etc/passwd.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-200"],"references":["https://huntr.com/bounties/a6b521cf-258c-41c0-9edb-d8ef976abb2a"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:08:41.295252406+00:00"},"epss":{"cve":"CVE-2025-6984","score":0.01647,"percentile":0.76296,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-pc6w-59fv-rh23","url":"https://osv.dev/vulnerability/GHSA-pc6w-59fv-rh23","summary":"Langchain Community Vulnerable to XML External Entity (XXE) Attacks","modified":"2026-09-10T03:50:28.568695973Z","packages":[{"ecosystem":"PyPI","name":"langchain-community","purl":"pkg:pypi/langchain-community","ranges":["<0.3.27"],"fixed":["0.3.27"]}]},{"id":"PYSEC-2026-1515","url":"https://osv.dev/vulnerability/PYSEC-2026-1515","summary":"Langchain Community Vulnerable to XML External Entity (XXE) Attacks","modified":"2026-07-07T17:46:46.938374274Z","packages":[{"ecosystem":"PyPI","name":"langchain-community","purl":"pkg:pypi/langchain-community","ranges":["<0.3.27"],"fixed":["0.3.27"]}]}],"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).
