Hidden Prompts Trick AI Into False Email Summaries

Researchers demonstrate that invisible HTML tags can be inserted into emails to influence artificial intelligence (AI)-driven summarization models. Attackers use these hidden prompts to cause the models to generate misleading or malicious content in the summary output. Organizations relying on automated email summarization should review input sanitization and model guardrails.

Why it matters: Security teams using AI-powered email summarizers face the risk of attackers injecting hidden HTML to produce false or malicious summary content, requiring immediate review of input filtering and model output controls.
