AI agents vulnerable to webpage instruction hijacking

A security researcher demonstrated how easily AI agents can be tricked into executing malicious instructions embedded within webpages. By including hidden commands in a webpage's footer, the agent can be prompted to ignore its original directives and send sensitive information, such as API credentials, to an attacker. While explicit "ignore previous instructions" commands are detectable, subtler, implicitly worded instructions are proving to be a more significant and unsolved security challenge for current AI agent architectures.
