{"id":"CVE-2026-19295","details":"IBM Langflow OSS 1.0.0 through 1.11.1 allows an authenticated attacker to execute arbitrary operating system commands in the server process by saving a flow with a crafted type field value and triggering a build of a wrapper flow that references it. This allowed privilege escalation from \"authenticated flow user\" to arbitrary OS-level command execution under the server process identity, bypassing the LANGFLOW_ALLOW_CUSTOM_COMPONENTS=false policy control.","modified":"2026-09-02T08:08:56.140118Z","published":"2026-08-28T22:16:47.613Z","references":[{"type":"ADVISORY","url":"https://www.ibm.com/support/pages/node/7284733"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/langflow-ai/langflow","events":[{"introduced":"24d9e86885b877ea3e9d03cbc50b963765489721"},{"fixed":"077ec9471636ba407005b6cd760e2195278de480"}],"database_specific":{"cpe":"cpe:2.3:a:langflow:langflow:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"1.0.0"},{"fixed":"1.11.2"}],"source":"CPE_RANGE"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-19295.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}
