Security SummaryAI

CVE-2025-68461 is a Cross-Site Scripting (XSS) vulnerability affecting Roundcube Webmail versions before 1.5.12 and 1.6 before 1.6.12. The issue stems from improper handling of the animate tag within an SVG document, classified under CWE-79. It carries a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N), highlighting its potential for cross-origin impact with low confidentiality and integrity effects.

Unauthenticated remote attackers can exploit this vulnerability over the network with low attack complexity and no user interaction required. Exploitation involves delivering a malicious SVG document containing an animate tag, enabling XSS payloads to execute in the context of the victim's browser session within the Roundcube Webmail interface.
