  • Sep 18, 2025PureVPN client applications on Linux through September 2025 mishandle firewalling.CVE-2025-59692 · Other software · PureVPN · reported by MITRELow 3.7

    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.

    PureVPN client applications on Linux through September 2025 allow IPv6 traffic to leak outside the VPN tunnel upon network events such as Wi-Fi reconnect or system resume. In the CLI client, the VPN auto-reconnects and claims to be connected, but IPv6 traffic is no longer routed or blocked. In the GUI client, the IPv6 connection remains functional after disconnection until the user clicks Reconnect. In both cases, the real IPv6 address is exposed to external services, violating user privacy and defeating the advertised IPv6 leak protection. This affects CLI 2.0.1 and GUI 2.10.0.

  • Apr 18, 2018PureVPN 6.0.1 for Windows suffers from a SYSTEM privilege escalation vulnerability in its "sevpnclient" service.CVE-2018-10204 · Other software · Purevpn · reported by MITREHigh 8.8

    PureVPN 6.0.1 for Windows suffers from a SYSTEM privilege escalation vulnerability in its "sevpnclient" service. When configured to use the OpenVPN protocol, the "sevpnclient" service executes "openvpn.exe" using the OpenVPN config file located at %PROGRAMDATA%\purevpn\config\config.ovpn. This file allows "Write" permissions to users in the "Everyone" group. An authenticated attacker may modify this file to specify a dynamic library plugin that should run for every new VPN connection attempt. This plugin will execute code in the context of the SYSTEM account.

  • Feb 25, 2018An issue was discovered in PureVPN through 5.19.4.0 on Windows.CVE-2018-7484 · Other software · Purevpn · reported by MITREHigh 7.8

    An issue was discovered in PureVPN through 5.19.4.0 on Windows. The client installation grants the Everyone group Full Control permission to the installation directory. In addition, the PureVPNService.exe service, which runs under NT Authority\SYSTEM privileges, tries to load several dynamic-link libraries using relative paths instead of the absolute path. When not using a fully qualified path, the application will first try to load the library from the directory from which the application is started. As the residing directory of PureVPNService.exe is writable to all users, this makes the application susceptible to privilege escalation through DLL hijacking.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
