CVE-2017-7839 created at 25 Sep 2019 19:31:40
Severity	+ Low
Remote	+ Remote
Type	+ Cross-site scripting
Description	+ Control characters prepended before javascript: URLs pasted in the addressbar in Firefox before 57.0 can cause the leading characters to be ignored and the pasted JavaScript to be executed instead of being blocked. This could be used in social engineering and self-cross-site-scripting (self-XSS) attacks where users are convinced to copy and paste text into the addressbar.
