Agentic attack surface expanding: Cisco +450% traffic per agentic task; Langflow vulns known-exploited went from 1 pre-2026 to 12 in 2026, with 15,000+ canary hits on three CVEs.

Quoted text

Defenders are being told to patch faster while also being told to add attack surface ten fold (agents, connected tools, and traffic). Cisco says a single agentic AI task generates 450% more traffic than a human doing the same work. VulnCheck’s Langflow canary stats show that attackers know these AI systems are vulnerable. Pre-2026: 1 Langflow vuln known exploited. 2026: +11 more exploited in the wild (12 total). Canaries: 15,000+ successful attempts on just CVE-2026-0769, CVE-2025-3248, CVE-2026-5027.

Analyst rationale

Trade-intel compilation. Not a named victim. Evidence that the complementary control (patch + isolate agent tools) is losing to the volume of new agent endpoints — injection and credential cards.
