In Roundcube Webmail before 1.6.17 and 1.7.x before 1.7.2, insufficient Cascading Style Sheets (CSS) sanitization in HTML e-mail messages may lead to SSRF or Information Disclosure, e.g., if stylesheet links point to local network hosts. NOTE: this issue exists because of insufficient fixes for CVE-2026-35540 and CVE-2026-48843.

Server-Side Request Forgery and information disclosure in Roundcube Webmail before 1.6.17 and 1.7.x before 1.7.2 arises from insufficient CSS sanitization in HTML e-mail bodies, letting a crafted message with stylesheet links pointing to internal hosts coerce the server into issuing requests to local-network resources. This is a re-opened flaw stemming from incomplete fixes for CVE-2026-35540 and CVE-2026-48843, indicating the sanitizer still failed to block specific local-address URL patterns. …
