CVE-2026-0770

CRITICAL 9.8 KNOWN EXPLOITED PoC CATALOGUED DETECTION TEMPLATE ALL-YEARS

Published 2026-01-23 · Last modified 2026-07-22 · zdi · NVD: Analyzed

Langflow exec_globals Inclusion of Functionality from Untrusted Control Sphere Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Langflow. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of the exec_globals parameter provided to the validate endpoint. The issue results from the inclusion of a resource from an untrusted control sphere. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-27325.
