High

Base vector

AV:N/AC:M/Au:N/C:N/I:C/A:N

Name of the Vulnerable Software and Affected Versions Firefox versions prior to 70

Description The issue is related to a lack of validation in the parent process of Firefox, which could allow an attacker to grant attacker-controlled permissions instead of the 'Click to Play' permission when a user accepts a permission request. This could potentially impact the integrity of data.

Recommendations For versions prior to 70, update to version 70 or later to resolve the issue. As a temporary workaround, consider disabling the 'Click to Play' feature until a patch is available. Restrict access to sensitive data and permissions to minimize the risk of exploitation.
