{"id":"DEBIAN-CVE-2026-88859","details":"A flaw was found in Evolution. A remote attacker can exploit this vulnerability by sending a specially crafted HTML email containing a spoofed vCard control. When a victim clicks on this control, Evolution's trusted JavaScript handler incorrectly assigns an attacker-controlled JavaScript URL to an iframe's source. This action leads to arbitrary JavaScript execution within the mail-viewing context, effectively bypassing the security measures designed to prevent script execution in email content.","modified":"2026-09-11T06:00:21.602545944Z","published":"2026-09-10T12:16:33.980Z","upstream":["CVE-2026-88859"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-88859"}],"affected":[{"package":{"name":"evolution","ecosystem":"Debian:12","purl":"pkg:deb/debian/evolution?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.46.4-2","3.46.4-2+deb12u1","3.47.2-1","3.47.3-1","3.48.0-1","3.48.1-1","3.48.2-1","3.48.3-1","3.48.4-1","3.49.2-1","3.49.2-2","3.49.2-3","3.49.3-1","3.50.0-1","3.50.1-1","3.50.2-1","3.50.3-1","3.51.2-1","3.52.0-1","3.52.1-1","3.52.1-2","3.52.1-3","3.52.1-4","3.52.2-1","3.52.2-2","3.52.3-1","3.53.2-1","3.53.3-1","3.54.0-1","3.54.1-1","3.54.2-1","3.54.3-1","3.54.3-2","3.55.1-1","3.55.1-2","3.55.2-1","3.55.3-1","3.56.0-1","3.56.1-1","3.56.2-1","3.56.2-10","3.56.2-2","3.56.2-3","3.56.2-4","3.56.2-5","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-2026-88859.json"}},{"package":{"name":"evolution","ecosystem":"Debian:13","purl":"pkg:deb/debian/evolution?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.56.1-1","3.56.1-1+deb13u1","3.56.2-0+deb13u1","3.56.2-1","3.56.2-10","3.56.2-2","3.56.2-3","3.56.2-4","3.56.2-5","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-2026-88859.json"}},{"package":{"name":"evolution","ecosystem":"Debian:14","purl":"pkg:deb/debian/evolution?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.56.1-1","3.56.2-1","3.56.2-10","3.56.2-2","3.56.2-3","3.56.2-4","3.56.2-5","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-2026-88859.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L"}]}
