CISA Chief Uploaded Sensitive Documents into Public ChatGPT

CISA's acting director reportedly uploaded sensitive, non-classified "for official use only" contracting documents into the public ChatGPT in mid-2025, which triggered multiple automated security alerts and prompted an internal DHS review. The documents were detected by agency sensors, leadership was briefed, and the incident raised concerns about potential exposure of sensitive information to external parties and model training, though no classified material or confirmed exploitation was reported.
