The Cognitive Firewall:Securing Browser Based AI Agents Against Indirect Prompt Injection Via Hybrid Edge Cloud Defense

Researchers developed the Cognitive Firewall, a hybrid edge-cloud defense system that protects browser-based AI agents from indirect prompt injection attacks. The three-stage architecture reduces attack success rates to below 1% while maintaining 17,000x faster response times compared to cloud-only solutions by processing simple attacks locally and complex threats in the cloud.

Atomicity for Agents: Exposing, Exploiting, and Mitigating TOCTOU Vulnerabilities in Browser-Use Agents

Researchers identified widespread TOCTOU (time of check to time of use) vulnerabilities in browser-use agents, where web pages change between planning and execution phases, potentially causing unintended actions. A study of 10 popular open-source agents revealed these security flaws are common, prompting development of a lightweight mitigation strategy based on pre-execution validation.
