By PulseAugur Editorial · [1 sources] ·

A security assessment by Tencent's AI-Infra-Guard team revealed that DeepSeek Harness is vulnerable to indirect prompt injection attacks, with success rates ranging from 17% to 25.5% across various channels. The study concluded that AI agents require controls to mediate between untrusted content and sensitive actions. In response, Correctover has developed CCS (Correctover Conformance Shape), a runtime verification layer designed to sit at the tool-call boundary and prevent dangerous actions or data leaks. AI
