The developer of fourpointo, a self-hosted AI-powered task checklist generator, conducted security tests on the application's upload pipeline. The tests focused on prompt injection and stored Cross-Site Scripting (XSS) vulnerabilities. Initial tests confirmed that the application's input validation, including magic-byte checks and an LLM-based content gate, effectively rejected malformed or non-assignment PDFs. Subsequent attempts to inject malicious instructions into PDF content to manipulate the LLM's output or to introduce XSS vulnerabilities were unsuccessful, indicating that the application correctly treats uploaded content as untrusted data.
