Hi, The following vulnerability was published for evolution. CVE-2026-88859[0]: | 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. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
