CVE-2016-1728 is a medium-severity vulnerability affecting Apple iOS before 9.2.1 and Safari before 9.0.3. It involves a flaw in the CSS implementation that mishandles the "a:visited button" selector during height processing, allowing remote attackers to more easily obtain sensitive browser history information via a crafted website. The attack requires user interaction (UI:R) and has a low impact on confidentiality (C:L), with no impact on integrity or availability. There is no evidence of active exploitation, and no public exploit code or Metasploit modules are available. Community discussion and media coverage are minimal, suggesting limited attention to this vulnerability.
