    Apple Multiple Products Use-After-Free WebKit Vulnerability — Apple iOS, iPadOS, macOS, and other Apple products contain a use-after-free vulnerability in WebKit. Processing maliciously crafted web content may lead to memory corruption. This vulnerability could impact HTML parsers that use WebKit, including but not limited to Apple Safari and non-Apple products which rely on WebKit for HTML processing. Listed in the CISA KEV catalog (added 2025-12-15) — confirmed exploited in the wild, not theoretical. FIRST EPSS puts the chance of exploitation in the next 30 days at ~9%. Treat it as real and prioritize remediation over triage.
