Base 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 59

Description The issue is related to WebExtensions using "view-source:" URLs to bypass restrictions, allowing them to view local "file:" URL content and content stored in "about:cache". This could enable a remote attacker to gain unauthorized access to protected information.

Recommendations For versions prior to 59, update to version 59 or later to resolve the issue. As a temporary workaround, consider restricting the use of WebExtensions that utilize the "view-source:" URL scheme until a patch is applied.
