Official description
Network-AI ClaudeHookBridge before 5.15.1 truncates the target string to 500 characters before evaluating denyPatterns, while Claude Code executes the full untruncated command. Attackers can position dangerous content past byte 500 in a Bash command field to bypass the operator's hard-deny list and execute arbitrary commands.
