CVE-2026-19624: Fedora Extra Packages For Enterprise Linux Epel

High severity, CVSS 7.8. EPSS: 0.1% chance of exploitation in the next 30 days.

A flaw was found in NetworkManager-l2tp. The plugin writes attacker-controlled VPN connection properties (vpn.data and vpn.secrets values) unescaped into a generated ipsec.conf file that pluto loads as root. A local unprivileged user can create and activate their own L2TP VPN profile containing a newline-injected leftupdown directive; pluto executes that command as root when the IKE security association is established, resulting in local privilege escalation. This is the same bug class as CVE-2018-10900 (NetworkManager-vpnc).

Affected products

• Fedora Extra Packages For Enterprise Linux Epel: from 1.20.0, before 1.20.24 (fixed in 1.20.24)
• Fedora Fedora: from 1.52.0, before 1.52.4 (fixed in 1.52.4)
