CVE-2026-88859

No fix known EPSS <1%CVSS 6.3

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.
