A path traversal vulnerability (CVE-2026-42048) has been disclosed in Langflow's Knowledge Bases API, allowing attackers to read arbitrary files on the server. The advisory (OSV GHSA-9whx-c884-c68q) was published on 2026-05-05. While Langflow has released subsequent PyPI versions (1.9.5, 1.9.6rc0, 1.9.6) around late May to early June, it is unclear if the vulnerability has been patched. Users are advised to update to a fixed version if available or to restrict API access. This security flaw may impact trust and adoption among enterprise users, especially those handling sensitive data.
