CVE-2024-37383Roundcube Webmail — animation attributes in a vector image

Roundcube Webmail before 1.5.7 and 1.6.7 lets animation attributes inside a vector image (SVG) carry script, which runs when the message is opened. A later release had to close the same hole again.

YOUR NEXT MOVE

Upgrade Roundcube to 1.5.7 or 1.6.7 now, then on to the later fix for the repeat of this; review mailbox rules for changes nobody made.
