Prompting      Prompting is just asking AI to do stuff but there is a massive difference between a vague request and a well-structured prompt.      A prompt is a call to action . If the pattern is vague , the AI has to guess what you mean. But the more focused and specific your prompt is, the better the results become. You are not exactly “ hacking probabilities ,” but you are giving the model better instructions to generate the output you actually want. 1. personas      Give the AI a role, personality, or level of expertise to influence how it responds and generates the result. Instead of just saying: “Explain Linux.” Try: “You are an experienced Linux instructor teaching beginners.”      Now the AI has a better idea of how to think about the response, who it is speaking to, and what kind of answer you expect. 2. context      LLMs can hallucinate. They are prediction machines that generate the most like...

n8n – CVE-2025-68613: Critical RCE Vulnerability

Image
    A critical vulnerability ( CVE-2025-68613 ) has been identified in n8n , the popular workflow automation tool. The flaw lies in the expression evaluation system, where user-supplied expressions can escape the sandbox and access Node.js internals. This leads to arbitrary code execution with a CVSS score of 9.9 (Critical) .      n8n is an open source workflow automation platform. Versions starting with 0.211.0 and prior to 1.120.4, 1.121.1, and 1.122.0 contain a critical Remote Code Execution (RCE) vulnerability in their workflow expression evaluation system. Under certain conditions, expressions supplied by authenticated users during workflow configuration may be evaluated in an execution context that is not sufficiently isolated from the underlying runtime. An authenticated attacker could abuse this behavior to execute arbitrary code with the privileges of the n8n process. Successful exploitation may lead to full compromise of the affected instance,...
