VentureBeat·high signal

Capsule Security launched April 15 with $7M seed (Lama Partners, Forgepoint Capital) to secure AI agents at runtime — monitoring actions between prompt and execution, detecting anomalous sequences, and enforcing real-time policy. Shipped ClawGuard, an open-source enforcer for OpenClaw that adds checkpoints before tool calls. Concurrently disclosed two zero-day vulnerabilities: ShareLeak (CVE-2026-21520, critical indirect prompt injection in Microsoft Copilot Studio) and PipeLeak (prompt injection in Salesforce Agentforce via untrusted lead-form inputs).
