What is the impact of this vulnerability? An attacker who successfully exploited the vulnerability could view some sensitive information (Confidentiality), make changes to disclosed information (Integrity), but cannot limit access to the resource (Availability). According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do? The user must visit the attacker‑controlled webpage, and perform the two tap gestures that cause autofill to activate. What is the version information for this release?
