Apple · Safari · CVE-2011-0242
**Name of the Vulnerable Software and Affected Versions**
Apple Safari versions prior to 5.0.6
**Description**
A cross-site scripting (XSS) issue allows remote attackers to inject arbitrary web script or HTML via vectors involving a URL that contains a `username`. This can be achieved by manipulating the URL to include malicious script or HTML, potentially leading to unauthorized actions on the affected system.
**Recommendations**
For versions prior to 5.0.6, update to version 5.0.6 or later to resolve the issue. As a temporary workaround, consider restricting access to URLs that contain user-supplied input, such as `username`, to minimize the risk of exploitation.
