What is CVE-2026-2604?

CVE-2026-2604 is a medium-severity path traversal vulnerability in GNOME Evolution Data Server, published on 16 Jun 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

Official description

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.

Weakness: CWE-73
