Google Chrome/ChromeOS sandbox side step via owning extensions

Kyle Osborn and Matt Johansen

Chrome OS replaces desktop programs with HTML and JavaScript extensions, so an XSS in an extension inherits whatever chrome.* API permissions its manifest.json declared. The paper shows an injected script calling chrome.tabs.executeScript across every open tab, and a wildcard match pattern letting XHR read the victim's Gmail, sidestepping the sandbox without any memory bug.
