Simulated file disclosure is not proof that a chatbot read a server file
Resecurity’s prompt-injection write-up highlights the need to distinguish generated output from demonstrated backend access.
What happened
Resecurity’s January 2026 write-up discusses prompt manipulation and a simulated /etc/passwd disclosure. A model producing plausible file-like text is not, by itself, evidence that it opened a real file on the host system.
A convincing security finding needs a demonstrated connection between model behavior and application impact: an actual tool call, verifiable private data or a controlled side effect. The article should not be recast as confirmed remote code execution or a named customer breach.
When testing chatbots, record the application’s tool activity and validate results independently. Report simulated output as simulation, and separate policy bypasses from unauthorized access to underlying systems.
Next step
Require verifiable tool activity or private-data evidence before claiming file access.
