signal brief

Langflow, an open-source visual AI workflow builder, has disclosed a wave of critical security vulnerabilities in June-July 2026, as recorded in multiple OSV advisories. The issues range from remote code execution (RCE) via validate_code() source 6 and CSV Agent source 12 to server-side request forgery source 3, path traversal in Knowledge Bases API source 8 and source 13, missing authentication on critical API endpoints source 5, and cleartext storage of authentication settings source 10. These vulnerabilities could allow attackers to execute arbitrary code, access sensitive data, or completely compromise Langflow instances. Notably, CVE-2024-9277 describes an inefficient regex complexity that could lead to denial of service source 2. A development release (1.12.0.dev8) was published on PyPI shortly after the advisories source 1, suggesting an ongoing fix effort, but the scale and severity of these issues erode user trust and raise adoption risk for enterprises relying on Langflow for production AI workflows.

What the sources said

  • OSV advisory PYSEC-2026-1525: "Langflow affected by Remote Code Execution via validate_code() exec()"
  • Advisory PYSEC-2026-1524: "Langflow Missing Authentication on Critical API Endpoints"
  • Advisory PYSEC-2026-2569: "Langflow vulnerable to injection"
  • PyPI release 1.12.0.dev8 published on 2026-07-28, likely containing security patches.
