ChatGPT File Download Vulnerability: Guardrail Bypass to Local File Inclusion — Technical Analysis and Mitigations
By
HackMoN Ai
Summary
Security researcher zer0dac discovered a vulnerability chain in OpenAI's ChatGPT platform that combines LLM social engineering (guardrail bypass via conversational framing) with a classic path traversal flaw in the file download endpoint. This allowed retrieval of restricted system files like /etc/passwd from the ChatGPT sandbox environment. The article provides a technical deep dive into the exploit mechanics, including inconsistent path normalization, and offers mitigation strategies.
