Impact
CVE-2023-5631 vulnerability was discovered in Roundcube.
Situation
Roundcube before 1.4.15, 1.5.x before 1.5.5, and 1.6.x before 1.6.4 allows stored XSS via an HTML e-mail message with a crafted SVG document because of program/lib/Roundcube/rcube_washtml.php behavior. This could allow a remote attacker to load arbitrary JavaScript code.
Call to action
The fix is expected in Plesk Obsidian 18.0.56 #2. Planned release date is October, 31.
Additionally, 18.0.56 #4 includes even newer Roundcube version 1.6.5.
Update Plesk to the latest version as soon as the fix is released.
