CVE-2016-2817 Mozilla: Elevation of privilege with chrome.tabs.update API in web extensions (MFSA 2016-46)
Last modified: 2016-05-09 00:52:28 EDT
Security researcher Muneaki Nishimura (nishimunea) of Recruit Technologies Co., Ltd. reported that the chrome.tabs.update API for web extensions allows for navigation to javascript: URLs without additional permissions. This can used to elevate privilege for a universal cross-site scripting (XSS) attack by a malicious web extension. It can also be used to inject content into other extensions if they load content within browser tabs. External Reference: https://www.mozilla.org/security/announce/2016/mfsa2016-46.html
