CVSS v2.0
7.8
High
| Vector | AV:N/AC:L/Au:N/C:C/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
Firefox versions prior to 85
Description
The issue is related to an ambiguous file picker design that could confuse users into uploading a whole directory instead of a single file. This could potentially allow a remote attacker to gain unauthorized access to protected information due to errors in the user interface's representation of information. The estimated number of potentially affected devices and details about real-world incidents where this issue was exploited are not provided.
Recommendations
For versions prior to 85, update to version 85 or later to address the issue. As a temporary workaround, consider using caution when selecting files for upload to avoid inadvertently uploading entire directories until the update is applied.
