Why it matters
Prompt injection via hidden white text and metadata in legal documents turns indirect prompt injection into a concrete document-review and litigation-integrity risk, showing eDiscovery and AI-review workflows must inspect hidden content and validate AI output against source.
EDRM analysis by Sheila Grela discusses real cases of indirect prompt injection in litigation, including a Connecticut sanctions decision (Elliott v. New York Bariatric Group) where a self-represented litigant embedded hidden white-text instructions in court filings directing any reviewing AI to produce favorable conclusions and treat prior rulings as errors. The court sanctioned the conduct and revoked electronic filing privileges, echoing an earlier Brazilian case with similar hidden prompts in filings.
