When `AUTO_LOGIN` was `False` (i.e., authentication was enabled), neither branch enforced an ownership check — the query returned any flow matching the given UUID regardless of who owned it.\n\nThis exposed any authenticated user to:\n\n- **Read** any other user's flow, including embedded plaintext API keys\n- **Modify** the logic of another user's AI agents\n- **Delete** flows belonging to other users\n\nThe vulnerability was introduced by the conditional logic that was meant to accommodate public/example flows (those with `user_id = NULL`) under auto-login mode, but inadvertently left the authenticated path without an ownership filter.\n\n---\n\n## Fix (PR #8956)\n\nThe fix removes the `AUTO_LOGIN` conditional entirely and unconditionally scopes the query to the requesting user:\n\n```diff\n-    auth_settings = settings_service.auth_settings\n-    stmt = select(Flow).where(Flow.id == flow_id)\n-    if auth_settings.AUTO_LOGIN:\n-        stmt = stmt.where(\n-            (Flow.user_id == user_id) | (Flow.user_id == None)  # noqa: E711\n-        )\n+    stmt = select(Flow).where(Flow.id == flow_id).where(Flow.user_id == user_id)\n```\n\nAll three operations — read, update, and delete — route through `_read_flow`, so the single change covers the full attack surface. A cross-user isolation test (`test_read_flows_user_isolation`) was added to prevent regression.\n\n---\n\n## Acknowledgements\n\nLangflow thanks the security researcher who responsibly disclosed this vulnerability:\n\n- **[@chximn-dt](https://github.com/chximn-dt)**","references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-34046","reference_id":"","reference_type":"","scores":[{"value":"0.00052","scoring_system":"epss","scoring_elements":"0.16672","published_at":"2026-06-05T12:55:00Z"},{"value":"0.00052","scoring_system":"epss","scoring_elements":"0.1663","published_at":"2026-06-07T12:55:00Z"},{"value":"0.00052","scoring_system":"epss","scoring_elements":"0.16668","published_at":"2026-06-06T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-34046"},{"reference_url":"https://github.com/langflow-ai/langflow","reference_id":"","reference_type":"","scores":[{"value":"8.7","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/langflow-ai/langflow"},{"reference_url":"https://github.com/langflow-ai/langflow/pull/8956","reference_id":"","reference_type":"","scores":[{"value":"8.7","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-03-31T13:57:05Z/"}],"url":"https://github.com/langflow-ai/langflow/pull/8956"},{"reference_url":"https://github.com/langflow-ai/langflow/security/advisories/GHSA-8c4j-f57c-35cf","reference_id":"","reference_type":"","scores":[{"value":"HIGH","scoring_system":"cvssv3.1_qr","scoring_elements":""},{"value":"8.7","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-03-31T13:57:05Z/"}],"url":"https://github.com/langflow-ai/langflow/security/advisories/GHSA-8c4j-f57c-35cf"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34046","reference_id":"","reference_type":"","scores":[{"value":"8.7","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34046"},{"reference_url":"https://github.com/advisories/GHSA-8c4j-f57c-35cf","reference_id":"GHSA-8c4j-f57c-35cf","reference_type":"","scores":[{"value":"HIGH","scoring_system":"cvssv3.1_qr","scoring_elements":""}],"url":"https://github.com/advisories/GHSA-8c4j-f57c-35cf"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/86224?format=json","purl":"pkg:pypi/langflow-base@0.5.1","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-4xn4-uppj-hqcp"},{"vulnerability":"VCID-qwtw-q92t-quhz"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/langflow-base@0.5.1"}],"aliases":["CVE-2026-34046","GHSA-8c4j-f57c-35cf"],"risk_score":4.0,"exploitability":"0.5","weighted_severity":"8.0","resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-1dek-kvzf-27d1"},{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/90147?format=json","vulnerability_id":"VCID-4xn4-uppj-hqcp","summary":"Langflow: DoS Through Lack of File Size Restriction via Deprecated Unauthenticated File Upload API\nA security flaw has been discovered in langflow-ai langflow up to 1.1.0.
