FortiBleed: Large-Scale Credential Harvesting Campaign Targeting 430,000+ FortiGate Firewalls Globally

A Russian-speaking initial access broker has been conducting a sustained credential-harvesting campaign against FortiGate firewalls since February 2026, compromising over 430,000 devices globally and harvesting approximately 110 million credentials. This represents a significant threat to enterprise network security infrastructure and likely serves as a precursor to deeper compromise or sale of access.

Langflow IDOR in Flow Access Control – Authentication Bypass via UUID-Based Direct Object Reference

An Insecure Direct Object Reference (IDOR) vulnerability in Langflow's `/api/v1/responses` endpoint allows authenticated attackers to access and execute flows owned by other users by manipulating flow UUIDs. The vulnerability bypasses user ownership validation when flows are referenced by UUID rather than endpoint name.

Langflow BaseFileComponent Arbitrary File Read Leading to Authentication Bypass and RCE

Path traversal via symlink injection in tar extraction allows unauthenticated file disclosure, JWT secret theft, and remote code execution in Langflow RAG deployments. Organizations must patch immediately as exploit chain is straightforward and affects multiple file-handling components.

CVE-2026-55447
Langflow (langflow/langflow), BaseFileComponent derivatives: DoclingInlineComponent, DoclingRemoteComponent, FileComponent, NvidiaIngestComponent, VideoFileComponent, UnstructuredComponent
