For years, our security team has run pentests against business-critical applications across industries, and one pattern stands out. The vulnerabilities that are the most difficult to remediate are business logic vulnerabilities: IDOR, broken access control, privilege escalation, and multi-step workflow abuse. These are the kind of vulnerabilities pentest experts find by noticing a broken assumption behind one API call and chasing it until the full exploit path becomes clear.

A critical remote code execution vulnerability has been identified in Langflow. The vulnerability was first reported to the vendor in mid-2025 and disclosed publicly as a zero-day in January 2026. Exploitation attempts rose sharply in late August 2026, moving from isolated probing to continuous, multi-source scanning within days.
