Information disclosure in Apple WebKit Web Inspector allows remote attackers to read sensitive information by processing web content. Apple states only that improved checks correct the Web Inspector issue and has not published the faulty operation or input validation condition. Exploitation requires user interaction with attacker-controlled web content, and the published impact is limited to confidentiality.
