Prompt injection via HTTP headers found across 217M web responses

Original: Prompt injection in HTTP headers: what 217M web responses show

A new analysis examined 217 million web responses to measure how often HTTP headers carry hidden instructions that could manipulate AI agents and browser assistants. The study highlights a growing security concern: as AI systems fetch and read web content automatically, malicious headers could steer their behaviour. Security practitioners are debating the scale of the risk and possible defences.

Why now: Rising use of AI agents that automatically read web content makes header-based prompt injection a timely security risk.
