Exposure of Sensitive Information to an Unauthorized Actor
WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6, and before 4.1 on Mac OS X 10.4, does not properly handle clipboard (1) drag and (2) paste operations for URLs, which allows user-assisted remote attackers to read arbitrary files via a crafted HTML document.
CWE-200 - Information Exposure
An information exposure vulnerability is categorized as an information flow (IF) weakness, which can potentially allow unauthorized access to otherwise classified information in the application, such as confidential personal information (demographics, financials, health records, etc.), business secrets, and the application's internal environment.
