Summary
A new arXiv paper describes Baya, a web agent built to resist prompt-injection attacks that hijack its control flow. The authors note that common web agents use the ReAct paradigm, which picks each action from runtime observations that mix trusted and untrusted content, leaving their control flow open to instructions embedded in webpages. Baya instead compiles its plan before accessing the live website, so the action sequence is fixed ahead of any untrusted page content. The snippet is truncated, so the full evaluation details are not available here.

What happened
Web agents commonly follow the ReAct paradigm, selecting each action from runtime observations that inherently mix trusted and untrusted content. This design makes their control flow vulnerable to prompt injections embedded in webpages. We introduce Baya, a compile-then-execute web agent designed to prevent...
Why it matters
Developers building agents that browse the web on users' behalf may need to consider architectures that separate planning from page content. Businesses deploying such agents could face fewer hijacking risks if this approach holds up in testing. Readers should watch for the paper's experimental results and whether other agent frameworks adopt a similar compile-first pattern.
