Name of the Vulnerable Software and Affected Versions Firefox versions prior to 56

Description The issue is related to the browser's behavior when web content is dragged onto certain parts of the browser UI, such as the tab bar. This can lead to the opening of links that would otherwise be restricted, potentially allowing malicious web content to open locally stored files through file: URLs. The vulnerability may also be exploited to conduct cross-site scripting attacks.

Recommendations For versions prior to 56, update to version 56 or later to resolve the issue. As a temporary workaround, consider avoiding dragging web content onto the browser UI to minimize the risk of exploitation. Restrict access to sensitive local files to prevent potential malicious activity.
