{"id":"DEBIAN-CVE-2026-2604","details":"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.","modified":"2026-09-26T08:47:43.358004005Z","published":"2026-06-17T13:20:15.937Z","upstream":["CVE-2026-2604"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-2604"}],"affected":[{"package":{"name":"evolution-data-server","ecosystem":"Debian:12","purl":"pkg:deb/debian/evolution-data-server?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.46.4-2+deb12u1"}]}],"versions":["3.46.4-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-2604.json"}},{"package":{"name":"evolution-data-server","ecosystem":"Debian:13","purl":"pkg:deb/debian/evolution-data-server?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.56.1-2","3.56.2-0+deb13u1","3.56.2-1","3.56.2-2","3.56.2-3","3.56.2-4","3.56.2-5","3.56.2-6","3.56.2-7","3.56.2-8","3.56.2-9"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-2604.json"}},{"package":{"name":"evolution-data-server","ecosystem":"Debian:14","purl":"pkg:deb/debian/evolution-data-server?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.56.2-8"}]}],"versions":["3.56.1-2","3.56.2-1","3.56.2-2","3.56.2-3","3.56.2-4","3.56.2-5","3.56.2-6","3.56.2-7"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-2604.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:H/A:L"}]}
