External protocol handler (tel:) address bar spoof

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

A malicious web page could open a tel link in a window that was showing a different website, causing the phone-call prompt to appear as if that site had requested the call. This vulnerability was fixed in Firefox for iOS 156.1.
