Summary

Network-AI from 5.14.0 before 5.15.2 has a bypass in the ClaudeHookBridge PreToolUse hook, which checks deny patterns only against the first candidate field present in a tool call. A prompt-injected agent can place dangerous payloads in other fields, such as Write content or an MCP script parameter, beside a benign file_path or command, which evades denyPatterns and allows web shells to be written or scripts executed. The weakness is CWE-436, Interpretation Conflict. An attacker needs local access and must be able to influence the agent's input; a successful attack can cause high confidentiality, integrity and availability impact.
