CVE-2018-5167
Additionally, the JavaScript debugger will display "javascript:" links, which users could be tricked into clicking by malicious sites.
Does this matter?
Lower severity and a low EPSS score (1.41%). Track it; it rarely justifies an emergency change on its own.
Description
The web console and JavaScript debugger do not sanitize all output that can be hyperlinked. Both will display "chrome:" links as active, clickable hyperlinks in their output. Web sites should not be able to directly link to internal chrome pages. Additionally, the JavaScript debugger will display "javascript:" links, which users could be tricked into clicking by malicious sites. This vulnerability affects Firefox < 60.
