{"id":"CVE-2026-33053","summary":"Langflow has Missing Ownership Verification in API Key Deletion (IDOR)","details":"Langflow is a tool for building and deploying AI-powered agents and workflows. In versions prior to 1.9.0, the delete_api_key_route() endpoint accepts an api_key_id path parameter and deletes it with only a generic authentication check (get_current_active_user dependency). However, the delete_api_key() CRUD function does NOT verify that the API key belongs to the current user before deletion.","aliases":["GHSA-rf6x-r45m-xv3w","PYSEC-2026-78"],"modified":"2026-05-20T08:11:18.414994216Z","published":"2026-03-20T06:53:48.471Z","database_specific":{"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33053.json","cwe_ids":["CWE-639"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33053.json"},{"type":"ADVISORY","url":"https://github.com/langflow-ai/langflow/security/advisories/GHSA-rf6x-r45m-xv3w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33053"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/langflow-ai/langflow","events":[{"introduced":"0"},{"fixed":"7f3b01629629d3229550259d2a969525b2a09391"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33053.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:L"}]}
