## AI overview

A security alert reports that Mist versions 0.8.6 and lower exposed low-level APIs that malicious DApps or webpages could use to access the computer's filesystem, delete files, launch protocol handlers, and obtain sensitive information. Users are advised to upgrade Mist and avoid untrusted webpages. Ethereum Wallet is not affected because it cannot load external DApps.
