CVE-2026-2604: Gnome Evolution Data Server

Medium severity, CVSS 5.6. EPSS: 0.3% chance of exploitation in the next 30 days.

A flaw was found in evolution-data-server. Inconsistent comparison logic in the addressbook file backend allows a Flatpak application with D-Bus access to craft a malicious URI containing directory traversal sequences. This URI is stored without proper validation during contact creation or modification. Later, during contact deletion, the URI is processed with a less strict check, leading to the deletion of arbitrary files on the host filesystem. This could potentially include critical Flatpak override files.
