Hi,

The following vulnerability was published for epiphany-browser.

CVE-2026-18487[0]:
| 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/](https://t
| rusted.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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
