#prompt-injection — 1sec.ai

I built an OpenAI compatible firewall for AI agents. Try to break it.

A developer created an OpenAI-compatible firewall for AI agents called Arc Gate. It analyzes entire sessions rather than individual prompts, tracking authority and escalating restrictions based on user behavior. The tool aims to prevent prompt injection attacks by monitoring multi-turn interactions. You can test the firewall on Reddit.

Key takeaways

Analyzes entire sessions, not just individual prompts.
Escalates restrictions from ALLOW to BLOCK based on user behavior.
Aims to prevent prompt injection attacks in multi-turn interactions.

Structural Role Injection in Handlebars-Templated LLM Prompts: Triple-Brace Interpolation, Delimiter Family, and the Limits of HTML Auto-Escaping

Researchers analyzed Handlebars templating engine's impact on structural role injection vulnerability in LLM prompts. The engine's double-brace and triple-brace interpolation methods affect prompt security. HTML auto-escaping provides partial protection but has limitations. You should understand these nuances when building LLM applications.

Key takeaways

Handlebars' triple-brace interpolation bypasses HTML auto-escaping.
Delimiter family affects structural role injection vulnerability.
HTML auto-escaping is not a comprehensive security solution.
