CVE-2020-26979 (GCVE-0-2020-26979)

Vulnerability from cvelistv5

Published

Modified

2024-08-04 16:03

Severity ?

CWE

When entering an address in the address or search bars, a website could have redirected the user before they were navigated to the intended url

Summary

When a user typed a URL in the address bar or the search bar and quickly hit the enter key, a website could sometimes capture that event and then redirect the user before navigation occurred to the desired, entered address. To construct a convincing spoof the attacker would have had to guess what the user was typing, perhaps by suggesting it. This vulnerability affects Firefox < 84.
