CodeSentinel: Three-Layer Defense Against Indirect Prompt Injection in Code LLMs

Wed, 17 Jun 2026 16:12:50 +0000

CodeSentinel is a three-layer inference-time sanitizer designed to protect large language models from indirect prompt injection attacks hidden in code contexts such as comments, strings, and identifiers. It uses Tree-sitter to identify high-risk code syntax tree nodes and applies sanitization to pr...

Risk-Aware Causal Gating Enhances LLM Agent Security via Tool Contract Integrity

Wed, 17 Jun 2026 00:00:11 +0000

Risk-Aware Causal Gating (RACG) protects tool-augmented large language model (LLM) agents from indirect prompt injection by restricting access to dangerous tools. This approach shifts the trust requirement to the integrity of the tool contracts rather than the agent's compliance alone.
