Detailsinfo

A vulnerability classified as problematic has been found in PureVPN Client Application CLI 2.0.1/GUI 2.10.0 on Linux. Affected is an unknown function of the component Network Traffic Handler. The manipulation with an unknown input leads to a resource transfer vulnerability. CWE is classifying the issue as CWE-669. The product does not properly transfer a resource/behavior to another sphere, or improperly imports a resource/behavior from another sphere, in a manner that provides unintended control over that resource. This is going to have an impact on integrity. CVE summarizes:

PureVPN client applications on Linux through September 2025 mishandle firewalling. They flush the system's existing iptables rules and apply default ACCEPT policies when connecting to a VPN server. This removes firewall rules that may have been configured manually or by other software (e.g., UFW, container engines, or system security policies). Upon VPN disconnect, the original firewall state is not restored. As a result, the system may become unintentionally exposed to network traffic that was previously blocked. This affects CLI 2.0.1 and GUI 2.10.0.
