CVE-2017-7763 describes a domain name spoofing vulnerability affecting Firefox, Firefox ESR, and Thunderbird on OS X. Certain Tibetan characters, when used in an Internationalized Domain Name (IDN) in the address bar, are rendered as whitespace due to default OS X fonts, allowing for visual deception. This medium-severity vulnerability (CVSS 5.3) has a low impact on integrity (I:L) and requires no user interaction (UI:N) or privileges (PR:N). There is no evidence of active exploitation, and no public exploit code (Metasploit, Nuclei, ExploitDB) is available. Community discussion and media coverage are minimal, with only one article mentioning the Firefox 54 release that patched this issue.
