firefox: JavaScript can be injected into an exported bookmarks file by placing JavaScript code into user-supplied tags in save...
CVE-2017-7840 is fixed in 4 products on 1 platform, first by firefox 57.0.1+build2-0ubuntu1, released June 11, 2018. It is not reported as exploited. Patch Radar priority: Routine.
JavaScript can be injected into an exported bookmarks file by placing JavaScript code into user-supplied tags in saved bookmarks. If the resulting exported HTML file is later opened in a browser this JavaScript will be executed. This could be used in social engineering and self-cross-site-scripting (self-XSS) attacks if users were convinced to add malicious tags to bookmarks, export them, and then open the resulting file. This vulnerability affects Firefox < 57.
