Information Disclosure

Description

An issue was discovered in Roundcube Webmail before 1.5.15 and 1.6.15. The remote image blocking feature can be bypassed via SVG content in an e-mail message. This may lead to information disclosure or access-control bypass. This involves the animate element with attributeName=fill/filter/stroke.

Analysis

Roundcube Webmail before versions 1.5.15 and 1.6.15 fails to properly sanitize SVG content in email messages, allowing the remote image blocking feature to be bypassed via SVG animate elements with malicious attributeName values. This vulnerability enables unauthenticated attackers to bypass access controls and potentially disclose information through image loading, affecting all Roundcube installations using vulnerable versions.
