NVD Description
Note: Versions mentioned in the description apply only to the upstream epiphany-browser package and not the epiphany-browser package as distributed by Debian.
See How to fix? for Debian:14 relevant fixed versions and status.
A flaw was found in Epiphany. An issue in how the browser reads web addresses allows attackers to fake the domain name shown in the address bar. If a user clicks a specially crafted link containing a colon (for example, https://trusted.com:80@attacker.com/), the address bar and security menus will display the safe website (trusted.com) but it will actually load the attacker website (attacker.com) on the screen. This allows attackers to create convincing phishing pages to trick users into trusting a malicious site.
