CVE-2025-11720

Spoofing risk in Android custom tabs

CVSS 8.1 HIGHEPSS 0.2%CWE-451

The Firefox and Firefox Focus UI for the Android custom tab feature only showed the "site" that was loaded, not the full hostname. User supplied content hosted on a subdomain of a site could have been used to fool a user into thinking it was content from a different subdomain of that site. This vulnerability was fixed in Firefox 144.
