Vulnerability AssessmentAI

Exploitation Exploitation requires the target user to actively navigate to attacker-controlled web content using Safari (or another WebKit-based browser, since iOS and iPadOS mandate WebKit for all browsers) on an unpatched Apple device. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 base score of 4.3 (Medium) accurately reflects a constrained denial-of-service scenario: the attack is network-reachable at low complexity with no privilege requirement (AV:N/AC:L/PR:N), but it mandates active user interaction (UI:R) and produces only availability impact at low severity (A:L), with no confidentiality or integrity consequences. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation The primary remediation is to apply the vendor-released patches: iOS 18.7.10 or iPadOS 18.7.10 for devices on the legacy 18.x branch, iOS 26.6.1 or iPadOS 26.6.1 for devices on the current 26.x branch, and macOS Tahoe 26.6.2 for Mac systems. … Detailed patch versions, workarounds, and compensating controls in full report.
