CVE-2018-5143 is fixed in 4 products on 1 platform, first by firefox 59.0.1+build1-0ubuntu1, released June 11, 2018. It is not reported as exploited. Patch Radar priority: Routine.
URLs using "javascript:" have the protocol removed when pasted into the addressbar to protect users from cross-site scripting (XSS) attacks, but if a tab character is embedded in the "javascript:" URL the protocol is not removed and the script will execute. This could allow users to be socially engineered to run an XSS attack against themselves. This vulnerability affects Firefox < 59.
