Summary
A vulnerability was found in WebKitGTK that allows remote, user-assisted information disclosure. The flaw is due to missing verification of the source of file drag-and-drop operations, enabling an attacker to read any file the user is permitted to access.
Risk Assessment
The risk involves potential leakage of sensitive user data, such as documents or system configurations, by abusing the file drag-and-drop mechanism in the browser.
Recommendation
It is recommended to immediately update WebKitGTK to the latest patched version. As a workaround, consider disabling file drag-and-drop support in the browser until the update is applied.
