Name of the Vulnerable Software and Affected Versions Mullvad VPN versions through 2024.1

Description The issue allows DNS traffic to leave the device when Mullvad VPN on Android fails to create a tunnel and does not set a DNS server in the blocking state. This can result in sensitive DNS requests being logged by operators of unintended DNS servers.

Recommendations For versions through 2024.1, as a temporary workaround, consider restricting DNS traffic until a patch is available. At the moment, there is no information about a newer version that contains a fix for this issue.
