Senserva AI Opinion for CVE-2026-0770
This Langflow flaw lets remote attackers pull in and run code from an untrusted source, giving them arbitrary code execution on the host with no authentication implied by its Critical CVSS 9.8 rating. Anyone running Langflow, the open source visual builder for LLM apps, is exposed, and CISA added it to the Known Exploited Vulnerabilities catalog on 2026-07-21 confirming attackers are already using it. Langflow instances are often stood up quickly for experimentation and left reachable, which makes them easy targets.
Do this: Locate every Langflow deployment, patch to the fixed release immediately, and take any internet exposed instance offline until it is updated.
