Airlock prompt injection vulnerability fixed in Hermes Agent plugin

By PulseAugur Editorial · [1 sources] ·

A security vulnerability was discovered in Airlock, a guardrail plugin for the Hermes Agent designed to prevent prompt injection. The vulnerability allowed an agent to exfiltrate data even when approval prompts were disabled, by exploiting a discrepancy in how unattended turns were registered. The issue was reported and fixed in Airlock version 0.2.3, with the maintainer implementing a more robust solution that checks Hermes's internal approval logic across various unattended modes. AI

IMPACT Highlights the need for thorough testing of unattended modes in AI agent guardrails to prevent data exfiltration.
