CVE-2025-6435

Name of the Vulnerable Software and Affected Versions: Firefox versions prior to 140

Description: The issue arises when a user saves a response from the Network tab in Devtools using the Save As context menu option. In this scenario, the saved file may not have the .download file extension, potentially leading to the user inadvertently running a malicious executable.

Recommendations: For versions prior to 140, update to version 140 or later to resolve the issue. As a temporary workaround, consider verifying the file extension of saved files from the Network tab in Devtools to avoid running malicious executables.
